Rubber sealing strips are diversified in materials, processes and structures, and different types of products have obvious differences in performance and applicable scenarios. Scientific classification and accurate scenario matching can effectively improve the sealing effect and service life of products, and reduce engineering and equipment maintenance costs. At present, the mainstream rubber sealing strips in the market are divided into four core categories: EPDM rubber, PVC rubber, silicone rubber and sponge rubber, each with independent performance advantages and fixed application fields, forming a complete sealing product system covering civil, architectural, industrial and high-end manufacturing scenarios.
EPDM rubber sealing strips are positioned as outdoor and architectural engineering special products, with outstanding weather resistance and aging resistance, suitable for building exterior walls, doors and windows, curtain walls, outdoor equipment and automobile exterior sealing. It is the first choice for energy-saving and durable sealing of civil and commercial buildings. PVC rubber sealing strips are positioned as indoor civil universal products, with high cost performance and rich styles, suitable for indoor doors, windows, furniture, cabinets and household electrical appliances, meeting daily indoor sealing needs. Silicone rubber sealing strips are high-end special products, suitable for high-temperature, hygienic and precision scenarios such as food machinery, medical equipment, ovens and high-end electronic equipment.
Sponge rubber sealing strips focus on buffer sound insulation and irregular gap sealing, suitable for scenarios requiring shock absorption, noise reduction and soft fitting, including indoor door and window noise reduction, mechanical equipment buffering, automobile interior gap sealing and box body shockproof sealing. In terms of structural classification, rubber sealing strips are divided into solid type, hollow type, multi-cavity type and special-shaped type. Solid type has strong wear resistance and pressure resistance; hollow type has better elasticity and sound insulation effect; multi-cavity type realizes multi-layer sealing and improves waterproof and wind resistance performance; special-shaped products are customized for special equipment and special gap sizes.
In practical engineering selection, indoor ordinary decoration prioritizes cost-effective PVC and sponge rubber strips, while outdoor architectural projects prefer weather-resistant EPDM strips. High-temperature, sanitary and precision industrial scenarios exclusively adopt food-grade and medical-grade silicone rubber strips. Precise matching between product types and application scenarios maximizes material performance, avoids premature sealing failure and reduces equipment and engineering maintenance costs. With the refined development of the sealing industry, customized classified rubber sealing strips have become mainstream, delivering targeted, professional sealing solutions for diverse industrial and architectural fields
