What is Silicone Rubber?

Silicone rubber is a high-performance synthetic elastomer known for its outstanding thermal stability and flexible properties. Unlike standard rubbers, it features a backbone of silicon and oxygen, allowing it to maintain its structural integrity and flexibility in environments where ordinary plastics and rubbers degrade.

Engineered for Extreme Conditions

When your project demands a material that won’t crack under freezing temperatures, melt under high heat, or fail when exposed to UV light and ozone, silicone rubber is the default industry choice. At Hexgon, we process it into precise custom shapes without compromising its natural durability.

Wide Temperature Range

Weather & Chemical Proof

Dielectric Properties

Stays fully flexible and functional from -50°C up to +200°C. It resists thermal aging and will not harden over time.

Highly resistant to UV radiation, ozone, moisture, and mild industrial chemicals. Excellent for long-term outdoor sealing.

Offers superior electrical insulation, making it the perfect choice for protective electronic grommets, boots, and terminal caps.

Manufacturing Capabilities

We don’t just supply raw stock. Hexgon provides custom processing to turn raw silicone rubber into production-ready parts using two primary methods tailored to your project volume:
  • Custom Silicone Molding: Best for complex 3D shapes, enclosures, and structural parts. We design and clean-cut tooling to ensure exact dimensional accuracy for low-volume batches.
  • Precision Die & Laser Cutting: Engineered for flat profiles, custom gaskets, shims, and seals. Ideal for quick-turn prototyping without upfront tooling costs.

Application-Specific Material Grades

  • Industrial Grade: Formulated for high mechanical strength, excellent tear resistance, and extreme insulation. Used for automotive seals, electrical grommets, and heavy machinery gaskets.
  • Food & FDA Grade: Formulated using non-toxic, odor-free ingredients that meet FDA compliance guidelines. Safe for food processing equipment, commercial kitchen seals, and packaging machinery.
  • Medical & Biocompatible Grade: High-purity, platinum-cured silicone designed for healthcare applications. Non-reactive, sterilizable, and suitable for fluid handling components and medical device seals.

Silicone Rubber Processing FAQs

Can you manufacture parts from standard 2D drawings or image files?

Yes. While 3D models allow for faster processing, our engineering team can work directly from 2D PDF blueprints, hand sketches, or reference images to bring your concept to life.

Do you require a Minimum Order Quantity (MOQ) for custom silicone molding?

No. We support everything from single-unit rapid prototypes to low-volume custom production runs with zero MOQ requirements.

How do you protect the privacy of my CAD blueprints?

All uploaded files, drawings, and corporate blueprints are treated with absolute confidentiality under strict internal data security protocols.
