①Performance and lifespan are comparable to sulfurized三元乙丙橡胶seal strips.
Self-adhesive rubber plastic thermal insulating strip wholesale supplierBody Part
Principle
Consisting of two parts: sealing and installation
Typically used within a range of -50 to 70°C.
Light in bulk density, high in tensile strength, and moisture-resistant (as an alternative to traditional materials like three-oil four-felt, asphalt wood shingles, etc.). The product is environmentally friendly, easy to install, and offers excellent waterproofing, leakage prevention, and water stoppage effects.
Corrosion-resistant, aging-resistant, withstanding extreme temperatures from +80℃ to -45℃ without dripping, deforming, or cracking, and long service life.
Features an independent perforated bubble structure; the specially designed seam board has a honeycomb-like pattern with uniformly distributed holes, which can bond tightly with cement or sealant without sanding, integrating seamlessly. It adapts to natural expansion and contraction changes, enhancing the sealing and water-stopping effect of the joint.

The products can be divided into solid-core items (such as round, square, and flat cross-section shapes), hollow items, and metal-rubber composite products. Among them, metal-rubber composite sealing strips account for over 60%. For rubber sealing strips, the design of the cross-section is crucial. First is the shape and size of the sealing lip, with both sides of the sealing lips contacting the glass from the sides of the car window with equal and appropriate force. The length and thickness of the lip should be appropriate; excessive thickness or length will increase the resistance of glass movement, while excessive thinness or shortness will result in poor guidance and sealing, causing vibrations, noises, and leakage. Next is the bottom shape and size of the cross-section, with protrusions on the car window steel channel cross-section for assembly of the guide slots. Therefore, the bottom of the guide slot cross-section should be designed with a corresponding structure that is easy to fit and utilizes the sealing strip's elasticity to attach to the steel guide slot, preventing it from falling out. Lastly, the shape and size of the outer edge are designed to improve the appearance, ensuring the guide slot's exterior surface is tightly fitted to the body.
