To reduce the plastic cost?1

Reduce the cost of plastic filling refers to the resin with low cost of packing, or add agent. Commonly used fillers are mainly natural mineral and industrial waste residue and so on, in addition to wood powder and nut shell powder, organic filler and thermosetting plastic waste powder, etc. Packing is the most widely used in plastic additives, consumption is the largest class of additives.

plastic filling for the purpose of thermoplastic plastics, mainly is to reduce cost; For thermosetting plastics is to reduce cost and modification. Can't fill in addition to reduce the cost, improve product performance. Generally can improve the rigidity, heat resistance, Inorganic filler) , dimensional stability, reducing forming shrinkage and creep resistance, etc. Some still can improve insulation, flame retardancy, smoke elimination and sound insulation, etc.

( 1) Packing oil-absorbing resin absorption and

a, oil-absorbing

b packing, packing resin absorption

in view of the packing with the above two kinds of oil absorption and resin absorption, the following points should be paid attention to when filling formula design.

a, formulation system containing liquid fertilizer, should choose oil-absorbing small packing.

b, formulation system containing liquid resin, resin absorption should be chosen small packing.

（ 2) Filler surface treatment

the purpose of the filler surface treatment is to reduce the packing of the hydrophilic, improve packing lipophilicity, thereby increasing the compatibility of filler with resin.

a, packing of coupling treatment

packing coupling refers to using coupling agent to add a method of material's surface activation treatment. Choose in specific coupling agent, the following should be paid attention to.

（ 一) Different packing variety of coupling agent

blending reduce the cost of plastic

blending reduce the cost of plastic resin with low price in the resin refers to the high prices or waste plastic, in order to achieve the purpose of cost reduction process.

and reduce the cost of plastic filling compared to the cost decline is not very big, but has the advantages of less influence on their own performance.

blending quality and resin used in resin, the resin price is relatively low, mainly: PVC, LDPE, LLDPE, HDPE, PP and PS seven, the so-called blending quality and resin is mixed with the resin.
