Material Classification

Two Core Silicone Technologies

We work with both Solid Silicone (HCR) and Liquid Silicone Rubber (LSR), selecting the optimal process based on your product's structure, hardness, and transparency requirements.

Solid Silicone (HCR)

High Consistency Rubber · 32 Machines

High-strength solid silicone ideal for products requiring excellent tear resistance and dimensional stability, such as swim caps and goggle straps.

  • Superior tear strength & tensile performance
  • Shore A 20-70 hardness range
  • Compatible with silk-screen & pad printing
  • Ideal: swim caps, straps, ear plugs, nose clips

Liquid Silicone (LSR)

Liquid Silicone Rubber · 17 Machines

Precision liquid injection enables ultra-fine detail, soft touch and crystal-clear transparency -- perfect for sealing rims and skin-contact components.

  • Ultra-soft touch (Shore A 10-40)
  • High transparency & color consistency
  • Automated, flash-free precision molding
  • Ideal: goggle gaskets, mask skirts, mouthpieces
Elasticity and rebound performance testing
Mechanical Performance

Softness, Elasticity & Rebound

Swimming equipment demands a precise balance between comfort and grip. Our silicone compounds are engineered for optimal softness while maintaining excellent elastic recovery -- ensuring goggles, caps, and straps retain shape after thousands of stretch cycles.

High Elastic Recovery

Up to 98% rebound rate -- maintains fit integrity even under repeated stretching.

Skin-Friendly Softness

Low Shore A hardness grades deliver a comfortable, non-irritating feel against skin.

Tear Resistance +45%

Enhanced polymer toughness extends product lifespan versus standard grades.

Environmental Resistance

Built to Withstand Pool Conditions

Chlorinated water, UV exposure and temperature cycling can degrade inferior polymers. Our silicone formulations are engineered specifically for prolonged aquatic use.

Chlorine Resistance

Non-reactive to pool chlorine and saltwater. Prevents yellowing, cracking, and odor over thousands of hours of exposure.

UV & Aging Resistance

Validated via accelerated aging tests. Retains color, flexibility and strength after extended outdoor and sun exposure.

Thermal Stability

Operational from −40°C to +200°C. Verified by constant temperature/humidity testing for global climate conditions.

Up to 92% light transmission in LSR grades.

Matte / Gloss / Soft-Touch

Surface finishes tailored to product category.

Multi-Color Molding

Two-shot, marbled & gradient effects available.

Post-processing options: silk-screen, pad printing, UV modification, laser engraving, and adhesive backing.

Validation Workflow

Sample Testing & Material Confirmation

Before any mass production commitment, we validate every material choice through a transparent, documented approval process.

01

Material Spec Review

We assess your performance, safety and visual criteria to shortlist candidate compounds.

02

Material Swatch Delivery

Physical samples with varied hardness, color and transparency are shipped for tactile review.

03

Prototype Testing

Tensile, tear, aging and chlorine immersion tests -- results reported in a signed QC document.

04

Final Confirmation

Approved specification locked and signed off. Mass production begins per ISO 9001 SOP.
