The silicone semi-lPNs consist of mixing a hydride-containing silicone prepolymer and a vinyl functionalized silicone polymer into a thermoplastic matrix such as PA, PBT, thermoplastic polyurethane (TPU) or styrene-ethylene/butylene-styrene (S-EB-S) block copolymer elastomer. The two silicone prepolymers co-react in the thermoplastic matrix during melt extrusion and injection molding to form a partially crosslinked network within the thermoplastic matrix. 

Rigid Thermoplastic Polyurethanes Rigid thermoplastic polyurethanes are not chemically cross-linked. Has high abrasion resistance, good retention of properties at low temperatures, but poor heat resistance, weatherability, and resistance to solvents. Rigid thermoplastic polyurethanes are flammable and can release toxic substances. Processed by injection molding and extrusion. Also called Rigid Thermoplastic Urethanes and Nonelastomeric Thermoplastic Polyurethanes.

Thermoplastic polyurethane elastomers are polymers that bridge the gap between rubbers and plastics. They can be used in a wide range of properties, from hard rubbers to soft engineering thermoplastics as they are elastic and melt-processable. They can be processed on extrusion as well as injection, blow and compression molding equipment. They can be vacuum-formed or solution-coated and are suited for a wide variety of fabrication methodologies. They provide a considerable number of physical property combinations high resilience, good compression set, resistance to abrasions, tears, impacts, weather, and even hydrocarbons. Such materials... 

Impact-resistant properties, especially at low temperatures, low-temperature toughness, melt-processing properties, and dimensional stability of thermoplastic polyurethane elastomers are improved by the addition of a carbonyl-modified polyolefin [54,55]. These improvements are particularly useful for reinforced polyurethanes. Small amounts of polyolefin homopolymer or copolymer with TPU blends are useful for molding plastic articles by injection molding, extrusion, calendering, or similar process for molding thermoplastic articles [56]. 

Thermoplastic polyurethane molding compounds are relatively nonelastic. They are available in blow molding, extrusion, and injection molding grades. Major suppliers of thermoplastic polyuiethaue include Dow Chemical (Isoplast) and LNP.

Pellethane thermoplastic polyurethane elastomers range from hard to soft and can be fabricated by a variety of methods, from injection molding to extrusion and blow molding. These elastomers offer a combination of properties rarely seen in an engineering thermoplastic. Table 16 gives descriptions and applications of Pellethane TPE-U products. 

Estane 58213 is processed by means of injection molding and general extrusion techniques. Estane 58213 NAT is a polyester-based thermoplastic polyurethane compound. The material can be used by itself or as a modifier of other polymers, such as PVC. Estane T-4057 black (Estane T4057 BLK 281) is a conductive, polyether-based thermoplastic polyurethane compound intended for extrusion applications. Estane T-4086 black (Estane T4086 BLK 281) is a conductive, polyester-based thermoplastic polyurethane. 

Irogran from Huntsman is a trade name of thermoplastic polyurethane elastomers, which are easily processed by injection molding or extrusion techniques. It is used when a maximum of mechanical strength is a basic requirments. Irogran materials combine an extreme wear resistance with high tear strength and mechanical reliability. Table 19 shows their typical properties.
