The differences, advantages and disadvantages of PP copolymerization and homopolymerization
2023-02-24
Polypropylene (PP) is divided into homopolymer polypropylene (PP-H), block (impact resistance) copolymer polypropylene (PP-B) and random (random) copolymer polypropylene (PP-R), so what are the advantages and disadvantages of all kinds of PP? I'll share it with you here. 1. Homopolymer polypropylene (PP-H) It is made by polymerization of a single propylene monomer. The molecular chain does not con...

In modified plastics, how long is the long glass fiber
2023-03-27
1. The optimum length of glass fiber in resin matrix The length of the glass fiber in the resin matrix is too short, only play the role of filler, not to strengthen the role; Too long, although the enhancement effect is significant, but affect the dispersion of glass fiber in resin matrix, molding processing performance and product performance. Therefore, it is generally believed that the ideal le...

The difference between high transparent PP and homopolymer PP
2023-05-11
1. Compare from transparency first Data show that the fog degree of high transparent PP is only 10%, the transmittance of more than 90%, and the fog degree of homopoly PP is 56%, that is to say, the transmittance of homopoly PP is only 44%. 2. From the appearance of glossiness The gloss of high transparent PP is 129.2%, while the gloss of homopolymer PP is only 99.6%. The gloss of high transparent...

How can ABS injection molded parts increase brightness?
2023-05-15
I. Injection moulds 1. Poor processing of mold cavity If the mold cavity has scars, microporous, wear, roughness and other deficiencies, it will inevitably react to the plastic parts, so that the plastic parts luster bad, for this, to carefully process the mold, so that the surface of the cavity has a small roughness, if necessary, polishing chrome plating. 2. cavity surface stains If the surface ...

A brief look at some of the key factors that make carbon fiber composites a viable alternative to traditional materials
2023-07-20
Nowadays, we find new uses for carbon fiber almost every day. These tiny filaments, which are currently available in a wide variety of functional shapes, have a diameter of one-tenth the thickness of a human hair. The fibers are processed into fabrics that can be used for molding subsequent molding processes and formed into tubes and sheets for construction, or as conventional threads for fiber wi...
