What is rubber vulcanizing agent HVA-2 (PDM) ?

 

Let's talk about the function of  Rubber Vulcanizing agent HVA-2 (PDM), CAS No. 3006-93-7,in this blog.

 

HVA-2

 

HVA-2 manufactured by Yangchen Tech can be used as both a vulcanizing agent and a co-vulcanizing agent in peroxide systems during rubber processing. It can also serve as a scorch retarder and tackifier. It is used in rubber components such as shoulder rubber and breaker layers in load-carrying tires to address shoulder voids in bias-ply truck tires. HVA-2 can also serve as a co-vulcanizing agent, improving related properties and thermal stability. It is suitable for high-temperature vulcanization systems, significantly reducing compression set. It can also reduce peroxide usage, prevent scorching during processing, and improve the bond strength between the rubber and cord and metal.

 

1. As a multifunctional rubber additive, HVA-2 can be used as both a vulcanizing agent and a co-vulcanizing agent in peroxide systems during rubber processing. It can also serve as a scorch retarder. It is suitable for general-purpose rubber, specialty rubber, and rubber-plastic hybrid systems.

 

2. In natural rubber, when combined with sulfur, it prevents reversion, improves heat resistance, reduces heat buildup, resists aging, and enhances rubber-cord adhesion and vulcanized rubber modulus. Used in rubber components such as shoulder rubber and cushioning media in load-carrying tires, it can address the shoulder void problem in bias-ply truck tires. It can also be used in large-format, thick-walled natural rubber products and various rubber miscellaneous products.

 

3. As a co-vulcanizing agent in specialty rubbers such as fluoroprene, fluorosulfonated polyethylene rubber, styrene-butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber, bromobutyl rubber, acrylic rubber, silicone rubber, and rubber-plastic blends, HVA-2 significantly improves related properties and heat resistance. It is suitable for high-temperature vulcanization systems, significantly reduces compression set, reduces peroxide usage, prevents scorching during processing, and enhances the bond strength between the rubber and cord and metal.

 

4. HVA-2 is a sulfur-free vulcanizing agent. It can replace all slag-containing vulcanizing agents such as those in cable rubber, and solves the problem of copper wire and copper electrical appliances being polluted by sulfur generated by connecting sulfur.
