Описание материалов:
Dynamically vulcanized thermoplastic (TPV) is a particular type of thermoplastic elastomer (TPE) which offers much better results given the exclusive combination of an elastomeric phase deeply dispersed in a continuous thermoplastic phase.
TPV Elastoprene® is a mixture of polypropylene and dynamically vulcanised EPDM rubber (PP/EPDM), with properties similar to those of other rubber products but with better results than traditional plastic materials. Its composition makes it compatible and particularly suitable for co-injection with polypropylene.
Due to the enormous advantages of processability, vulcanized rubber materials are being substituted by TPV Elastoprene®, using the traditional technology in the transformation of plastic. Furthermore, with the excellent properties obtained, TPV Elastoprene® is replacing plastic materials like PVC.
TPV Elastoprene® is completely recyclable and reusable, safe to the environment, thus improving the overall profitability of the process; an added advantage to rubber production and manufacture.
TPV Elastoprene® has good resistance to the effects of the ozone, UV and diverse chemical products, with an operating temperature from -60 to 135°C.
APPLICATIONS
The excellent properties of this material make it ideal for the demanding requirements of the automobile industry. Its principle application is for al types of molded parts for injection and overmolding with PP, for both the interior and exterior of vehicles.
In the construction industry, it can be used for supports and sealing profiles.
It can also be used for membranes, wheels and overmolding on handles for tools, electrical appliances and all types of consumer goods.
