Accelerator PDM supply _ Durbar chemical (certified) _ accelerator PDM

 Rubber accelerator PDM applications in natural rubber and tire using PDM with a small amount of peroxide initiator and crosslinked natural rubber or cis polyisoprene rubber tires can improve the heat resistance and close focus, and make vulcanized rubber has excellent flex fatigue resistance and elasticity. In particular, does not produce sulfide reversion phenomenon at 183 ℃, and permanent deformation. With the advantages of PDM / DCP system when vulcanized natural rubber as follows: ① can achieve high-temperature short-time vulcanization, 170 ℃ × 3min have a fairly good physical and mechanical properties; ② at high temperature vulcanization conditions, including PDM plastic material regardless of DCP, DM DTDM as initiator or accelerator PDM, will not appear reversion phenomenon; vulcanization curve is very flat. PDM system and sulfur vulcanized natural rubber rheometer curve (170 ℃) 1; sulfur accelerator PDM vendors, 2; promote DM, 1; D accelerator pro PDM pictures, 0.2; 2PDM, 3.5; DCP, 0.3; 3PDM, 3.5; promote DM, 0.8; 4PDM, 3.5; promoting TMTD, 0.8; PDM active in radical reactions and ionic reaction initiator (thiazole and sulfenamide accelerator) presence has been greatly improved, resulting in natural rubber heat resistance greatly improved. The use PDM- accelerator - sulfur system: sulfur accelerator PDM supply, 2; promoting CZ, 0.5; PDM, 3.0; permanent deformation of vulcanized rubber and its small permanent compression deformation, high strength and hardness. After persulfate remains high hardness and resistance to fatigue and tear resistance.
