1.PVC resin SG-7,K 60, or SG-5 mix with SG-8 2.PVC stabilizer Lead based one pack PVC stabilizer or Ca/Zn stabilizer, Funcation:Prevent the heat decomposition of PVC resin. Help the product to form 3.Chemical Foaming agent AC blowing agent.NC blwing agent( white blowing agent), AC foaming agent belongs to the exothermic foaming agent, NC foaming agent belongs to the endothermic foaming agent 4.Foaming regulator Funcation: improve the melt strength of the melt and prevent the merger of the bubbles, so as to get the PVC foaming products with uniform foaming. At the same time, it can also promote the plasticization of PVC to ensure that the melt has good fluidity. 5.lubricants processing aid ACR175 Promoting plasticiation, stripping between materials and metals ,keep the material better fluidity 6.Lubtricant G60 It is internal lubricants promoting plasticization, improving polymer fluidity and improving the surface finish of products. 7 PE WAX It is external lubricants,Reduce the friction between the polymer and the surface of the machine to prevent it from adhering to the mechanical surface 8.AC316A OR OA-6 It is high melt point ope wax, have good internal and external lubricants in middle and late processing 9.titanium dioxide ,optical brithener ,Ultramarine As pigment ,let product more white, and look blue shade 10.Filler Usually used coated calcium carbonate,Filler caco3 can inrease strengh of foaming board,can reduct cost of PVC foam board Whatsapp&wechat:+86-13563682728 E-mail:mandyzhang@novistagroup.com
