Silikonipin

Silikonipin is a cylindrical fastener or spacer made from silicone elastomer or coated with silicone polymer, used in non-metallic and mixed-material assemblies. The term is common in technical catalogs to denote pins that provide electrical insulation, chemical resistance, and low-wear bearing surfaces, reducing wear on mating parts.

Materials and properties: Core material is silicone elastomer, produced by room-temperature vulcanizing (RTV) or molding. Pins can be standard or medical/food-grade, with smooth or textured finishes. Hardness typically 20–60 Shore A. Temperature tolerance generally -60 to +250 C, depending on formulation; silicone resists many chemicals and is an excellent electrical insulator, though some hydrocarbons may swell it.

Manufacturing and variants: Manufactured by molding or extrusion, then cut to length and finished as needed. Some variants use reinforcement or lubricious coatings for improved wear. Typical sizes range from a few millimeters to centimeters, with tolerances matched to the assembly.

Applications: Used as alignment dowels, cushions, or insulating spacers in plastic housings, electronics enclosures, and automotive interiors. They reduce scratching, dampen vibration, and maintain precise fits without metal-to-metal contact; can serve as sacrificial pins in tools.

Safety and regulation: Silicone materials are generally biocompatible and chemically inert, but end-use grade selection and regulatory approvals vary. Processing waste is largely inert; recycling options are limited, so disposal should follow local guidelines.
