Precision Rubber Components
Engineered to Your Specs
We manufacture high-quality rubber moulding components strictly to customer drawings, samples, or specifications. From standard O-Rings to complex custom-engineered parts, we deliver reliability and precision for every application.
Material Reference & Technical Data
The following table presents key technical parameters for rubber grades used in our manufacturing process. All values are indicative; actual properties depend on compound formulation and processing conditions.
| Code | Material Name | Temp. Range | Hardness | Tensile Str. | Elongation | Colour | Primary Applications |
|---|---|---|---|---|---|---|---|
| NBR | Nitrile Butadiene Rubber | -40°C to +120°C | 30–90 Shore A | ≥ 15 MPa | 300–500% | Black / Any | Oils, fuels, hydraulic fluids, automotive seals |
| EPDM | Ethylene Propylene Diene | -50°C to +150°C | 40–90 Shore A | ≥ 10 MPa | 200–500% | Black / Grey | Water, steam, ozone, outdoor, HVAC |
| FKM | Fluorocarbon (Viton®) | -20°C to +200°C | 60–90 Shore A | ≥ 10 MPa | 150–350% | Black / Brown | Aggressive chemicals, high-temperature sealing |
| Silicone | Silicone (VMQ) | -60°C to +200°C | 20–80 Shore A | 5–10 MPa | 100–800% | Any | Food grade, medical devices, electrical insulation |
| CR | Chloroprene (Neoprene) | -40°C to +120°C | 40–80 Shore A | ≥ 14 MPa | 300–600% | Black | Weather, ozone, moderate oil exposure |
| NR | Natural Rubber | -55°C to +80°C | 30–80 Shore A | ≥ 20 MPa | 400–700% | Amber / Black | High elasticity, vibration damping, general use |
| PU | Polyurethane | -30°C to +80°C | 60–98 Shore A | ≥ 25 MPa | 300–600% | Yellow / Black | High abrasion, hydraulic cylinders, wear parts |
| PTFE | Polytetrafluoroethylene | -200°C to +260°C | 55–65 Shore D | 14–35 MPa | 200–400% | White | Chemical resistance, low friction, high-temp seals |
