Shanghai Daoqin Plastics Co., Ltd.

filling reduce plastics cost is in resin in add cost low filler, or is add agent. commonly used filler main/primary is 天然矿 material and industrial waste and other, in addition also has powder and housing/shell powder and other has machine filler and waste hot solid property plastics powder and other. filler is plastics additives in application most 广泛, consumption amount most large type additives.

plastics filling for/regarding thermoplastic property plastics, main/primary is reduce cost; for/regarding hot solid property plastics is reduce cost and modified has 之. filling remove reduce cost outer, can improvement products certain property can. can improvement has rigid property, heat resistant property （无 machine filler ）, dimensional stability, reduce molding shrinkage and resistant creep property and other; has also can improvement insulation property, flame retardant property, property and property and other.

commonly used filler

（1）天然矿 material type filler

a, CaCO3 type filler

b, slip powder filler

c, silicon filler

d, high filler

e, filler

f, silicon filler

filling reduce plastics cost formulation design key points

（1） filler property and resin property

a, filler property

b, filler resin property

鉴于 filler tool has upper types property and resin property, in filling formulation design attention/notes below/following 几点.

a, formulation system in has liquid additives 时, need selection property small filler.

b, formulation system in has liquid resin 时, need selection resin property small filler.

（2） filler surface treatment

filler surface treatment in reduce filler hydrophilic water property, improve/increase filler hydrophilic property, from increase large filler resin versus property.

a, filler 偶联处理

filler 偶联处理 is use coupling agent for material surface active 化处理 一 types methods. in specific selection coupling agent 时, attention/notes lower 几点.

（a） different filler product types selection coupling agent different

blending reduce plastics cost

blending reduce plastics cost is in high resin in mixed low resin or waste plastics, to reduce cost process.

and filling reduce plastics cost versus ratio its cost decline degree separation large, tool has for its property can effect/influence relatively small advantages.

blending resin

in use resin in, versus for low resin main/primary is: PVC, LDPE, LLDPE, HDPE, PP and PS七 types, blending resin mixed this resin.
