As a professional silicone manufacturer, we share 5 simple ways to check silicone gasket quality. You can judge reliability by these 5 core performance indicators. All tips help you pick reliable products in daily purchasing.
1. Wear Resistance Performance
First, check surface wear resistance.
High-quality gaskets stand up to friction well. Their surface patterns, prints and colors stay stable for long.
- Poor Quality: Easily fades, wears off or deforms after friction.
2. Elasticity Performance
Next, test overall elasticity.
Premium gaskets have excellent flexible rebound. This comes from stable silicone molecular chains.
- Quick Rebound: Directly shows high-quality raw materials.
- Poor Quality: Loses shape quickly or cannot bounce back.
3. Fatigue Resistance Ability
Besides, test fatigue resistance.
Good gaskets handle repeated stress changes well. They stay stable under continuous stretching and pressing.
- Poor Quality: Degrades fast after frequent use. Serious fatigue damage will greatly shorten service life.
4. Tear & Tensile Strength
Moreover, check tear and tensile strength.
High tear strength means strong damage resistance. Premium gaskets work stably for a long time.
- Poor Quality: Cracks easily under force. Cracks spread fast and cause complete breakage.
5. Hardness & Tensile Stress at Elongation
Finally, verify hardness and tensile strength.
Hardness reflects material rigidity. Tensile stress shows the force for deformation.
- Stable Data: Means qualified raw material formula.
- Standard Parameters: Guarantee stable sealing performance.
