Product Details
Introduction
Rubber vulcanizer HVA-2 (PDM) is a multifunctional rubber additive. It can be used as a vulcanizer, a vulcanizer for peroxide systems, and a scorch retarder and tackifier to improve the bonding strength between rubber and cord and metal. Yellow or brown powder, specific gravity 1.44, soluble in tetrahydrofuran and hot acetone, insoluble in petroleum ether, chloroform, benzene and water, melting point above 195°C.
Application
As a multi-functional rubber additive, HVA-2 can be used as a vulcanizing agent in the rubber processing process, and can also be used as a vulcanizing agent in the peroxide system. It can also be used as an anti-scorch agent and a tackifier. It is suitable for general-purpose rubber. It is also suitable for special rubber and rubber-plastic combined systems.
Application for natural rubber
Combined with sulfur, it can prevent vulcanization from returning to its original state, improve heat resistance, reduce heat generation, resist aging, and improve the adhesion between rubber and cord and the modulus of vulcanized rubber. It is used in rubber such as load-carrying tire shoulder rubber and buffer layer to solve the problem of shoulder space in bias-ply load-carrying tires. It can also be used in large-sized thick products of natural rubber and various rubber miscellaneous products.

Application for ulfur-free vulcanizing agent
HVA-2 is a sulfur-free vulcanizing agent used for cable rubber. It can replace all sulfur-containing vulcanizing agents such as thiazole and thiuram. It solves the problem of copper sulfide contamination and blackening of copper wires and copper electrical appliances due to contact with sulfur-containing vulcanizing agents. problem.
