Discussion on the Material of Hexagon Screw

Hexagon screw refers to the hexagon head mechanical plastic screw-front tooth (inch system), which has excellent insulation performance, non-magnetic, heat insulation, and light weight. The plastic screws of individual materials also have high temperature resistance, high strength, and corrosion resistance. Features, hexagon screws are widely used in various industries.

Hexagon screw-front tooth (co-British) material is divided into RENY glass fiber reinforced polyamide MXD6 polystyrene PPPS polyvinyl chloride PVC polyvinyl chloride PVC polyvinyl chloride resin PVDF polyethylene resin PTFE polycarbonate PC nylon 6/6 ceramic (alumina 96%)CA and so on.

RENY is a polymer based on polyamide MXD6, which is a 50% glass fiber reinforced crystalline engineering plastic. Due to the high strength and elasticity of engineering plastics, excellent flow resistance and heat resistance, it has replaced metal materials. Hexagon screws are widely used in parts of automobiles and other transportation tools, ordinary machinery, mechanical parts, electrical and electronic equipment parts, and civil construction parts Wait.

Polystyrene sulfide (PPS) is a crystalline special engineering plastic. The heat resistance is strong, and the physical properties are hardly deteriorated even when used in a high temperature atmosphere for a long time. In addition, it has good chemical resistance, mechanical properties, electrical properties and dimensional stability. Hexagon screws are widely used in electrical appliances, auto parts, chemical machinery parts, etc.

Polypropylene (PP) is a crystalline resin and is a representative general-purpose plastic. The specific gravity is 0.9, which is light in ordinary plastics, has good chemical resistance, water resistance and electrical properties, and is widely used in various fields. Polypropylene is a compound with good rigidity and toughness at high temperatures. It can be used in steam sterilization. It has wear resistance, friction coefficient, water absorption, good electrical properties, unique bending properties, excellent fire resistance and stress unevenness.

Polypropylene is also a high surface gloss material. Polypropylene has high tensile strength in olefin products, and the tensile coefficient of polypropylene is high, but the impact resistance is relatively weak. Polypropylene due to fatigue resistance, wear resistance, friction coefficient is very low, comparable with nylon. However, nylon has lubricity and wear resistance better than polypropylene. Polypropylene has good chemical resistance, can resist dilute acid, concentrated acid (except oxidizing acid), alkali, alcohol, detergent and water. Polypropylene is resistant to attack by aromatic compounds, chlorine compounds, oils, and oils at room temperature.
