Frequently Asked Questions

Q: What is the difference between EPDM and Silicone Seal Pads?                                    

EPDM is ideal for general-purpose weatherproofing and chemical resistance (up to 150°C), while Silicone offers superior high-temperature performance (up to 200°C) and extreme cold resistance (down to -60°C).

Q: Can these Seal Pads help my product achieve an IP67 rating?                                    

Yes, our Seal Pads are specifically engineered to create moisture-proof and dust-proof barriers for battery compartments and electronic housings, which are essential for achieving IP65, IP66, and IP67 certifications.

Q: How do Seal Pads prevent motor shaft failure?                                    

They form a tight, flexible seal that prevents internal lubricant from leaking out while blocking external contaminants like dust and water from entering the bearings, thus reducing wear and preventing premature failure.

Q: What chemicals are these Seal Pads resistant to?                                    

Our Seal Pads are designed to resist acetic acid, bleach, common detergents, ammonia water, and sea salt crystals, making them ideal for intelligent cleaning equipment and marine applications.

Q: Do you support custom shapes and hardness levels?                                    

Absolutely. We offer full customization of sizes, geometries, and Shore A hardness levels using precision die-cutting and molded designs to fit your specific structural requirements.

Q: What is "Compression Set" and why does it matter for sealing?                                    

Compression set is the permanent deformation of a material after being compressed. A low compression set means the Seal Pad recovers its shape efficiently, ensuring a consistent, tight seal over years of use.
