We offer plastic screws/bolts/nuts made from various materials.
Plastic screws have high electrical resistance and excellent insulation properties. By using plastic screws with superior insulation, it is possible to prevent short circuits. ● Heat Resistance: Materials such as PPS (polyphenylene sulfide) and RENY (polyphenylene sulfide-based resin) have a heat resistance temperature of over 200°C, providing stable performance even under harsh temperature conditions. ● Insulation: Plastic screws have low thermal conductivity and excellent insulation properties. They can prevent localized condensation caused by thermal bridges. Efficient thermal management can be achieved in the design of equipment and devices where temperature control is crucial. ● Lightweight: Plastic screws are very lightweight, making them suitable for products and equipment where weight reduction is necessary. ● Corrosion Resistance: Plastic screws do not rust or corrode, offering excellent resistance to moisture and chemicals. ● Electrical Insulation: Plastic screws have high electrical resistance and excellent insulation properties. By using plastic screws with superior insulation, it is possible to prevent short circuits.
