Abstract: An injection molding grade PVC tube and a method for producing the same are provided. The injection molding grade PVC tube includes 100 parts by weight of a PVC resin, 2 to 8 parts by weight of a heat stabilizer, 1 to 20 parts by weight of a first additive, and 0.7 to 15 parts by weight of a second additive. The first additive includes a processing modifier and a heat resistance enhancer, and a weight ratio between the processing modifier and the heat resistance enhancer is within a range from 1:6.67 to 1:10. The PVC resin, the heat stabilizer, the first additive, and the second additive are powder-shaped. The injection molding grade PVC tube is formed by direct injection molding after hot melt extrusion of the PVC resin, the heat stabilizer, the first additive, and the second additive.

Abstract: A polyethylene terephthalate composite material containing glass fiber and a method for manufacturing the same are provided. The polyethylene terephthalate composite material includes 40 to 65.5 parts by weight of polyethylene terephthalate, 5 to 40 parts by weight of the glass fiber, and 0.15 to 2.5 parts by weight of a crystallizing agent. The crystallizing agent includes an inorganic crystallizing agent and an organic crystallizing agent, and an added amount of the inorganic crystallizing agent is less than an added amount of the organic crystallizing agent.

Abstract: A composition and a manufacturing method of a highly flame-retardant and low-smoke injection-molded polyvinyl chloride pipe are provided. The composition includes a polyvinyl chloride resin material, a chlorinated polyvinyl chloride resin material, a flame retardant additive and a carbon forming additive. A first number-average degree of polymerization (DPn) of the polyvinyl chloride resin material is between 600 and 1,000. A second number-average degree of polymerization of the chlorinated polyvinyl chloride resin material is between 600 and 800. A difference between the first number-average degree of polymerization and the second number-average degree of polymerization is within 400. The flame retardant additive is a phosphorus-containing flame retardant modified by a modifier. A total added amount of the flame retardant additive and the carbon forming additive in the composition is not greater than 3 PHR.

Abstract: A fiber composite material is provided. The fiber composite material includes 40 phr to 65 phr of a polypropylene resin, 30 phr to 60 phr of a long glass fiber, 0.5 phr to 5 phr of a black masterbatch, and 0.5 phr to 10 phr of a compatibilizer. The black masterbatch contains carbon black having a basic active group on a surface of the carbon black. The compatibilizer is grafted with maleic anhydride.
