Component Specifications

Definition
The silicone body is the core component of silicone seal rings, manufactured from silicone rubber compounds through molding processes. It functions as the elastic element that creates and maintains a seal between mating surfaces by deforming under compression to fill gaps and prevent fluid or gas leakage. This component is engineered to withstand specific temperature ranges, chemical exposures, and mechanical stresses while maintaining its sealing properties over extended service life.
Working Principle
The silicone body operates on the principle of elastic deformation under compression. When installed between mating surfaces, it compresses to fill surface irregularities and create a continuous barrier. Its elasticity allows it to maintain sealing force despite thermal expansion, vibration, or minor surface movements, while its material properties resist degradation from environmental factors.
Materials
High-purity silicone rubber (VMQ) with specific formulations: typically 40-80 Shore A hardness, containing silica fillers for reinforcement, and may include additives for UV resistance, flame retardancy, or food-grade compliance. Common grades include FDA-approved, USP Class VI, or automotive-grade silicone compounds.

Frequently Asked Questions

What temperature range can silicone bodies withstand?

Standard silicone bodies typically operate from -60°C to +230°C continuously, with short-term exposure up to 300°C possible depending on formulation.

Are silicone bodies compatible with food processing applications?

Yes, when manufactured with FDA-approved or food-grade silicone compounds that meet relevant regulatory requirements for direct or indirect food contact.

How does hardness affect silicone body performance?

Harder silicone bodies (higher Shore A) provide better resistance to extrusion and higher pressure capability but require greater compression force. Softer bodies seal more easily on rough surfaces but may extrude under high pressure.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
