Changshu smoothly da plastic products factory of PVC plastic sheet in secure agent type

PVC plastic sheet with good chemical stability, corrosion resistance, high hardness, strength, high strength, anti ultraviolet ( Ageing resistance) , fire flame retardant ( Has the self-extinguishing) , insulation performance is reliable, the surface is bright and clean level off, not bibulous, not deformation, easy processing, etc. Replacing part of stainless steel and other corrosion resistance composite materials are widely used in chemical, petroleum, electroplating, water purification treatment equipment, environmental equipment, mining, medicine, electronics, communication, and decoration industries. Manufacturing PVC plastic sheet is inseparable from the stable agent, the safe agent on commonly used PVC plastic plate, on the basis of changshu smooth plastic products factory for many years of practical experience, safe agent there are two main types.



a safe system, lead salt, this kind of safe agent is mainly low thermal stability effect is good and the price level of strength, is one of the most commonly used type, suitable for some opaque and compare products are temporary, and are some of the products down on toxicity of demand is not high for use.



2, organic tin heat stable system, if this kind of the most secure system about the effect of thermal stability good analogy, but the price is more expensive than lead salts, and organic tin in secure system itself is no smooth effect, plus the smooth agent
