Product function:

As a multifunctional rubber additive, HVA-2 can be used as a vulcanizing agent , as a vulcanizing agent for peroxide systems, and as a scorch retarder and tackifier. For conventional rubber, it is also suitable for special rubber and rubber-plastic blends.

应用领域：                                                                                                                              

1.HVA-2在NR中，与硫磺配合，能防止硫化返原，改善耐热性，降低生热，耐老化，提高橡胶与帘子线粘合力和硫化胶模量。用于载重轮胎肩胶、缓冲层等橡胶中。可解决斜交载重轮胎肩空难题，也可用于天然橡胶的大规格厚制品及各种橡胶杂品。
2.HVA-2在CR、CSM、SBR、NBR、EPDM、IR、IIR、BIIR、ACM、SIR和橡塑合金等橡胶中,作为辅助硫化剂，能显著改善交联性能，提高耐热性，适用于高温硫化体系，降低压缩永久变形十分明显，还能减少过氧化物的用量，防止胶料在加工过程中的焦烧，提高胶料和帘子线及金属的粘合强度。
3.HVA-2属无硫硫化剂，用于电缆橡胶，它可以代替噻唑类、秋兰姆类等所有含硫硫化剂，解决了铜导线和铜电器因接触含硫硫化剂生成硫化铜污染发黑的难题。
4.HVA-2用于高档热溶性油漆、涂料，可大幅提高产品的耐热性、光亮度和与金属的粘合牢度；用于胶粘剂，可大幅度提高胶粘剂的耐热性和与金属的粘和牢度；由于本产品是优异的高分子耐热助剂，也可用于航空航天的耐热材料。 

Application :                                                                                                                                                      

1. HVA-2 in NR, combined with sulfur, can prevent vulcanization and reversion, improve heat resistance, reduce heat generation, anti-aging, improve rubber and cord adhesion and vulcanization modulus.
2. HVA-2 is used as an auxiliary vulcanizing agent in rubbers such as CR, CSM, SBR, NBR, EPDM, IR, IIR, BIIR, ACM, SIR and rubber-plastic alloys to significantly improve cross-linking properties and improve heat resistance. It is suitable for high temperature vulcanization system, which is very obvious to reduce the compression set. It can also reduce the amount of peroxide and prevent the scorch of the rubber during processing.
3.HVA-2 is a sulfur-free vulcanizing agent for cable rubber. It can replace all sulfur-containing vulcanizing agents such as thiazoles and thiurams, and solves the problem that copper wires are blackened by contact with sulfur-containing vulcanizing agents. problem.
4.HVA-2 is used for hot-melting paints and coatings, which can greatly improve the heat resistance, brightness and adhesion to metal of products. It can be used for adhesives to greatly improve the heat resistance of adhesives and metals. Adhesive fastness; because this product is an excellent polymer heat-resistant additive, it can also be used in aerospace heat-resistant materials.
