Mechanical equipment sealing strip

Product Introduction

1, mechanical sealing ring is a kind of widely used in various industrial equipment seals, it can effectively prevent the leakage of liquid, gas or dust from the equipment, but also can prevent the outside material into the equipment.

2. Mechanical seal strip (machinery rubber seal strip) is mainly used for cabinets and machinery. The main production materials are ethylene propylene diene monomer (EPDM), PVC, nitrile rubber, silicone rubber, etc. Mainly play a fixed, sound insulation, waterproof, dustproof, insect-proof, sealing and other functions.

3. Applicable temperature range

PVC MATERIAL -20 ° ℉-150 ° ℉(-29 ℃-65.5 ℃)

EPDM MATERIAL -40 ° ℉-248 ° ℉(-40 ℃-120 ℃)

NBR Material -40 ° ℉-248 ° ℉(-40 ℃-120 ℃

Silicone rubber -40 ° ℉-260 ° ℉(-40 ℃-126.6 ℃)

4. EPDM rubber sealing ring product characteristics

1) Light bulk density, high telescopic strength, and no water absorption. Product environmental protection, simple construction, anti-seepage, anti-leakage, good water effect.

2) EPDM sealant strip has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and room temperature fluidity. EPDM strips can be used for a long time at 120°C and can be used briefly or intermittently at 150-200°C. Adding suitable antioxidant can increase its use temperature. EPDM rubber crosslinked with peroxide can be used under harsh conditions. EPDM rubber can reach more than 150h without cracking under the condition of ozone concentration and 30% stretching.

3) has good weather resistance, ozone resistance, water resistance and chemical resistance. Can be used for alcohols and ketones, but also can be used for high temperature water vapor environment sealing. Suitable for circulating bath equipment, car radiator and car brake system. Not recommended for food use or exposure to mineral oil. The general use temperature range is -55~150 ℃
