We are one of the most famous manufacturers of Aramid fibe, Silicone Rubber and Red Phosphorus Based Flame Retardant masterbatch in China. For Aramid fiber, there are several grades available for reinforcement in civil industry and military industries; There're LSR and HTV silicone rubbers for especially electrical abd electronic applications.And we have several varied red phosphorus flame retardant masterbatches available to different compound systems as fire proof agent, therefore there?s need concerning about the compatibility. At the same time, we could supply GM Series Of Silicone Additive for Plastics working as lubricant, one component and two components room temperature vulcanized silicone rubber for sealant, adhesive and moulding, MCA, MPP.
