Super toughness PPS
Product features
This product is a new type of super tougheness polyphenylene sulfide of modified materials. The material has excellent chemical resistance, softness and impact strength, and it still remains heat resistance of the general PPS.
Product applications
The application areas of this product include: sealing element, wire and cable, car parts, hot oil (oil) extraction pipelining, also can be used as high temperature-resistant fabric with industrial fiber production parts. The color of BZ-T itself is close to pure white, easy to mix with pigment and can be used for color coding wire insulation materials. In addition, excellent properties such as the toughness, high strength and corrosion-resistance of BZ-T resins (even under high-temperature) will bring more choices to plastic processing plants and OEM.
