Product Description

Product Overview

Solid colored silicone round rods (solid silicone round bars/silicone dense round strips) are manufactured via high‑temperature extrusion from high‑purity silicone rubber, resulting in a fully solid, pore‑free structure. They are available in a variety of colors achieved through food‑grade, environmentally friendly color masterbatches. Combining elasticity, temperature resistance, electrical insulation, and excellent sealing properties, these rods serve as versatile elastic components for industrial sealing, home appliances, electronics, food‑processing equipment, and vibration damping applications. Customization is available for all standard specifications, colors, and hardness levels.

Core Material and Grading

General‑purpose industrial‑grade silicone rubber

Sealing for general-purpose equipment, impact protection for doors and windows, mechanical cushioning, and electrical insulation—offering excellent cost-effectiveness, oil resistance, and aging resistance.

Food-grade silicone (LFGB / Food Contact Certification)

Non-toxic, odorless, and free of leachables; safe for contact with food, baking equipment, drinking water appliances, and infant‑care accessories.

High-Temperature-Resistant, Flame-Retardant, Conductive Silicone (Customized Version)

The flame-retardant version is suitable for high-temperature ovens and baking chambers; the conductive version is designed for antistatic electronic workstations and cable protection.

Core Physical Performance Advantages

Ultra-wide temperature tolerance range

Normal use: 60°C to 200°C; short-term peak temperatures can reach 250°C. It remains flexible in extreme cold, does not melt at high temperatures, and emits no odors.

High elasticity and tear resistance, with long-lasting resilience.

Standard hardness: Shore A 30–80, adjustable; elongation at break ≥250%; resistant to deformation and cracking under repeated compression; excellent compression recovery.

Weather-resistant and anti-aging

It resists cracking and fading under prolonged exposure to sunlight, rain, and ozone, with a service life far exceeding that of ordinary rubber or PVC round rods.

Waterproof, acid- and alkali-resistant, slightly oil-resistant

The dense, solid structure provides excellent sealing, effectively blocking moisture, dust, and weak acids and bases, making it ideal for kitchens, bathrooms, and chemical‑processing equipment.

Insulated, flame-retardant, safe and environmentally friendly

Excellent insulation performance; halogen-free and phthalate-free; food-grade, suitable for boiling and high-temperature sterilization; the flame-retardant version self-extinguishes upon removal from the flame.

Easy to process and easy to clean

The surface is smooth and resistant to dust adhesion; simply wipe with clean water. It can be cut, bonded, and sanded, making it suitable for on-site fabrication.

3. Food and Beverage Equipment

Oven door seals, sealing gaskets for milk tea machines and water purifiers, non-slip bars for baking tools, and anti‑collision buffer components for food‑processing equipment.

4. Doors and windows, furniture, automobiles

Door and window anti-collision soundproofing strips, cabinet door shock-absorbing buffers, automotive window seals, and dashboard anti-slip stoppers.

5. Daily use, handicrafts, and tools

Yoga resistance sticks, handmade DIY soft rubber rods, medical device cushioning components, non-slip rubber strips for fishing gear, and soft rubber accessories for toys.

6. Equipment Vibration Damping and Cushioning

Machine tool vibration isolation pads, conveyor line anti-collision rubber strips, and noise-reducing support round rods for fans.
