Silicone solutions|Seals & Profiles

Why silicone?

Silicone is a highly versatile elastomer valued for its exceptional temperature resistance, elasticity, and long service life. At Trelleborg, we engineer silicone sealing solutions for reliable performance across industries, from automotive to food and beverage processing.

Wide temperature resistance

Performs reliably from -60°C to +200°C (-76° F to +392° F), making it ideal for aerospace and automotive environments.

Excellent UV & ozone resistance

Withstands outdoor exposure in construction and renewable energy applications.

Non-reactive &
chemically stable

Suited to sensitive environments including food and beverage processing and cleanrooms and medical-grade applications.

Long-term elasticity

Keeps its flexibility and sealing force over time, even under compression.

Flame retardant options

Formulation available in formulations that meet fire safety standards for critical applications.

Color & transparency options

Customizable for aesthetic or functional requirements.

Silicone material types

Two material forms. One high-performance family.

What is HTV (High-Temperature Vulcanizing) silicone?

HTV is a solid silicone rubber with high consistency, processed by extrusion and compression molding. Its mechanical strength and proven performance in demanding environments make it a dependable choice for profiles and larger parts.
Benefits of HTV sealing profiles:

High consistency: uniform, reliable material.
Versatile processing: extruded or compression molded to suit the application.
High mechanical strength: withstand mechanical stress in demanding conditions.
Broad size range: Suited from sealing profiles to larger molded components.
Proven performance: Dependable in demanding environments.

What is LSR (Liquid Silicone Rubber)?

LSR is a two-part liquid silicone system, mixed 1:1 and processed by injection molding. Its excellent flow and high repeatability make it well suited to precise sealing components with complex geometries.
Benefits of LSR sealing components:

Complex geometries: excellent flow fills intricate molds, enabling detailed and highly engineered designs.
Precision & repeatability: delivers consistent part quality from one cycle to the next.
Efficient production: Ideal for efficient, tightly controlled molding of finished components.
Clean, automated processing: supports a clean, consistent and automation-ready production process.
