Abstract: A matte synthetic paper is a biaxially oriented polypropylene synthetic paper having a thickness of 25 to 300 μm, and includes a printing surface layer as an outermost paper layer. Moreover, by adding a mist flour or a thermoplastic elastomer, the haze and gloss of the printing surface layer can be improved. According to Tappi T480, the printing surface layer having gloss of 15 to 50% is suitable to be printing paper.

Abstract: A composition and a manufacturing method of a highly flame-retardant and low-smoke extruded polyvinyl chloride pipe are provided. The composition includes a polyvinyl chloride resin material, a flame retardant additive and a carbon forming additive. The polyvinyl chloride resin material is in an amount between 10 PHR (parts per hundred resin) and 90 PHR. The flame retardant additive is in an amount between 0.5 PHR and 2.0 PHR, and is a phosphorus-containing flame retardant modified by a modifier. The carbon forming additive is in an amount between 0.2 PHR and 1.0 PHR. The carbon forming additive is at least one material selected from a group consisting of zinc chloride, zinc stearate, calcium stearate, zinc hydroxystannate, anhydrous zinc stannate, zinc phosphate and zirconium phosphate. A total added amount of the flame retardant additive and the carbon forming additive in the composition is not greater than 3 PHR.

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 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.
