Plei-Tech® 22 offers excellent abrasion and solvent resistance compared to other polyurethane compounds. Images: bhakpong â stock.adobe.com, During the mixing process, it is strongly recommended to work extremely thoroughly. Standard color is natural (cream), however color coding is available. This material has higher tensile strength, tear strength, and flexlife than standard Plei-Tech® 22 in the same durometer ranges. It is possible that the PU resin may crystallize slightly during storage. The final strength, i.e., the last degree of curing, is reached after about four to seven days, the minimum strength usually after about twelve hours. The most commonly used rubbers are also artificially made but there's also natural rubber. … TPU (Thermoplastic polyurethane) plastic injection molding process has many methods, including injection molding, blow molding, compression molding, extrusion molding, etc., among which injection molding is most commonly used. The areas of application for PU resin are incredibly diverse. PleiTech® 00 falls short of Plei-Tech® 22, Plei-Tech® 23, Plei-Tech® 24, Plei-Tech® 25 and Plei-Tech® 15 in solvent resistance. Typical applications are bumpers, diaphragms, rollers, and hydrocyclones. These plastics are separated into six different series, highlighted below. Polyurethane Rubber Tubes Use these tubes as jackets, seals, and insulation in areas where rubbing and scraping could cause wear on rubber. However, if you want to cast polyurethane, there are two things to consider: Fields of application for mold casting are, among others, the following: mold casting enjoys great popularity both in industry and among small users and can be carried out not only by machine but also by hand. Color is natural which is light brown that turns to dark brown when exposed to UV light.

Otherwise, the polyurethane casting resin may lose its favorable properties. Polyurethane is an extremely versatile elastomer used in countless applications worldwide. Polyurethane 1K Glue. Polyurethane casting resin is a fascinating material for both industry and the do-it-yourselfer. Maximum service temperature is 200°F. Kormax Polyurethane […] Plei-Tech® 23 is a polyester polyurethane. It is important that the casting resin is carefully mixed and poured slowly into the mold; otherwise, too many air bubbles will be added. Thermoset polyurethanes have many advantages over plastics for a variety of applications, including: How exactly you process PU casting resin naturally depends on its intended use. Casting resin for Making models, molds, protoypes, figurines, proof molds, make reproductions, etc.. Model-Pro turns from liquid to solid in 15 minutes and works excellent in silicone molds. This product has tremendous dynamic performance and abrasion resistance and is used where high frequency low loads are present. (ASTM D2842) Standard Test Method for Water Absorption of Rigid Cellular Plastics - This test method covers the determination of the water absorption of rigid cellular plastics by measuring the change in buoyant force resulting from immersion under a 5.1-cm (2-in.) Plei-Tech® 95 falls slightly short of other Plei-Tech® compounds in abrasion and cut resistance. Polyurethane coatings are ideal for surfaces that need abrasion resistance. Plei-Tech® 95 is a polyether polyurethane. In general, PUR casting resin should be stored at a temperature of 15 to 25 degrees Celsius in closed containers. This product has general MSHA approval. Model-Pro is a two component polyurethane casting resin which exhibits good impact resistance and strength. Unlike thermoset polyurethane, plastics will tend to remain permanently deformed or even break when stretching, abrasion or impact forces are applied. Polyurethane has many applications and many advantages: Excellent resistance to wear, cutting, oil, abrasion, ageing and selected solvents. After curing, soft materials are indicated in Shore hardness A and harder materials in Shore hardness D. The former have a rubber-like consistency. In outdoor applications, it should be preferred over epoxy resin coating because, unlike the latter, it does not have a tendency to yellow due to its high UV resistance and can also withstand sharp temperature fluctuations optimally. For example, foams can be produced from PU, but also paints, adhesives, and coatings. They are unique in combining the strength of rigid plastics with the flexibility and elasticity of rubber. This material is ideal for bumpers and cushions which require high displacements. (No properties are lost in this color transformation. Polyurethane is a polymer composed of organic units joined by carbamate links. Polyurethane 1K adhesives consist, as the name suggests, of only one component. But let’s keep it simple. Maximum service temperature 190°F. There are also color pigments and fluorescent dyes that can give the polyurethane resin a specific color. Such properties can be investigated and compared between different products using standardised test methods. Color is natural which is light brown that turns dark brown when exposed to UV light. Plei-Tech® 22 is not suited for applications involving high dynamic loading. Excellent resistance to thermal shock. There are several different resins available on the market, and each type has its advantages and disadvantages – including polyurethane casting resin. … The chart below show the physical properties of polyurethane. Typical applications are scrapers, snow plows, and squeegees. Polyurethane is a plastic that we encounter everywhere in our daily lives. Parts made of polyurethane will often outwear other materials by a margin of 5 to 50/one when severe abrasion is a factor. Polyurethane Rubber Rods Stronger than natural rubber, these polyurethane rods combine the shock-absorbing qualities of rubber with the tear resistance of plastic. Plei-Tech® 00 offers outstanding tear strength, good abrasion resistance, excellent resistance to oil products, and is suited for moderate dynamic loading. This compound is MSHA approvable. Usually it is a polymer. When you use ABS plastic, you get a material that is impact, chemical, and heat resistant. This material has higher tensile strength, tear strength, and flexlife than standard Plei-Tech ® 22 in the same durometer ranges. Typical applications are bumpers, balls, and hydrocyclones. Maximum service temperature is 200°F. Polyurethane resin coatings are also often used in kindergartens and schools, as they reduce the risk of slipping and accidents. Plei-Tech® 95 is available in hardnesses from 80°A to 75°D. Approximate Compression Deflection Plei-Tech® 22 is available in hardness from 40°A to 60°D. Thermoset Polyurethane VS Plastic . Polyurethane tubing merges properties of both rubber and plastic and is known for its exceptional toughness and tensile strength. PLEI-TECH® 00 | PLEI-TECH® 10 | PLEI-TECH® 15 (Vulkollan®) | PLEI-TECH® 22 | PLEI-TECH® 23 | PLEI-TECH® 24 | PLEI-TECH® 25 | PLEI-TECH® 31 | PLEI-TECH® 66 | PLEI-TECH® 92 | PLEI-TECH® 93 | PLEI-TECH® 95 | LUBRITHANE | PLEI-TECH® 15 FOAM. In contrast to the production of foam, where a reaction with water and the resulting foam formation is desired, in all other applications, the surfaces with which the liquid PU resin comes into contact should be completely dry. Like all polymers, its performance comes from its molecular make-up. (Click Graph to Enlarge). Available from 60°A to 88°A, and can be colored. However, PU also protects electronic assemblies from a wide range of environmental influences such as mechanical stress or moisture. Polytek ® 's two-part, room-temperature curing polyurethane plastics are available in varieties that can be poured, brushed or sprayed to create castings with unlimited versatility.. Oil and solvent resistant Polyurethane has excellent resistance to oils, solvents, fats, greases and gasoline. The physical properties of polyurethane are considerable. Also, you may want to use our Plastic Material Selection Guide or Interactive Thermoplastics Triangle to assist with the material selection process based on your application requirements. The casting resin offers significant advantages, as it is easy to apply and very durable. Color is black. Examples of fillers are, among others, cotton flocks, glass fibers, mineral fillers, and lightweight fillers. As a result, this can be made very variable to suit any application. Lubrithane is ideal for belt scraping applications because of good abrasion resistance and a low coefficient of friction. If you want to work with such a resin, you must, therefore, pay attention to the pot life, otherwise the material hardens too quickly, and you have to start again from the beginning. Make sure that the packaging is airtight and moisture-proof when opened. In our polyurethane resin guide, we assume its use as a floor coating on concrete as well as mold casting.
