High-Density Self-Adhesive Backing EPDM Rubber Weather Stripping Door Seal

High-Density Self-Adhesive Backing EPDM Rubber Weather Stripping Door Seal is a sealing product specially designed for sealing doors, windows, vehicles and equipment openings. It has excellent properties of high elasticity, weather resistance, UV resistance and waterproofness, and is widely used in homes, cars, construction and industry.

EPDM (ethylene propylene rubber) is a high-quality synthetic rubber with excellent weather resistance, heat resistance, ozone resistance and aging resistance. It adopts self-adhesive backing design, which can be installed without the use of additional glue or tools, and is easy to operate and has strong adhesion. The high-density structure further improves its sealing performance and can effectively block airflow, dust, noise and moisture.

Main features and parameters of the product
In the industry, common parameters and characteristics of High-Density Self-Adhesive Backing EPDM Rubber Weather Stripping Door Seal include:

Material characteristics
Material: EPDM rubber (Ethylene Propylene Diene Monomer)
Density: High-density design, usually between 0.9~1.2 g/cm³, ensuring high elasticity and excellent sealing effect.
Hardness: Usually between 50~80 Shore A, the specific hardness is adjusted according to different application scenarios. Too low hardness will affect durability, too high will reduce the sealing effect.
Temperature range: -40°C to 120°C, it can still maintain elasticity and sealing performance under extreme conditions.
Aging resistance: EPDM has very good anti-aging, anti-UV, anti-ozone and anti-oxidation properties, suitable for long-term outdoor use.
Weather resistance: Excellent weather resistance, able to resist aging due to long-term exposure to sunlight, wind and rain and harsh environments.

Adhesive properties
Adhesive: High-quality self-adhesive adhesive, usually acrylic-based adhesive or silicone adhesive, ensures strong adhesion and durability.
Adhesive strength: The adhesive strength of the adhesive can usually reach 10~15 N/25mm, ensuring that the sealing strip is fixed for a long time without falling off.
Temperature resistance: The adhesive part also has a wide temperature resistance range (for example **-20°C to 80°C**), ensuring that it can still maintain strong adhesion at different temperatures.

Dimensions
Thickness: The common thickness range is 2mm to 10mm, and the specific thickness is designed according to application requirements.
Width: The common width range is 5mm to 30mm.
Length: The length of a single roll is usually 5 meters, 10 meters, 25 meters, etc., which can be customized according to customer needs.
Shape: A variety of cross-sectional shapes are available, including D-type, E-type, P-type, V-type, I-type, etc., to adapt to different door and window or equipment gaps.

Application scenarios
High-density self-adhesive EPDM rubber sealing strips are widely used in multiple industries and scenarios, mainly including:

Home building field
Door and window sealing: Used for sealing gaps between indoor and outdoor doors and windows to prevent cold air, dust, and rain from entering, and to improve thermal insulation and sound insulation.
Wind and rain protection: Especially suitable for sealing external doors and windows to prevent wind and rain from invading, especially in areas with changeable weather.

Automotive industry
Car door and window sealing: The sealing strips of car doors and windows can effectively reduce wind noise and reduce external dust from entering the car compartment, while improving the efficiency of air conditioning.
Trunk sealing: Prevent water vapor and dust from entering the trunk and protect items in the car.

Electrical equipment sealing
Air conditioners, refrigerators and other equipment sealing: Provide good sealing effect, prevent cold air from leaking, and save energy and protect the environment.
Industrial machinery: Used for sealing mechanical equipment to prevent dust and moisture from invading and extend the service life of equipment.

Marine equipment and ships
Ship door and window sealing: Due to EPDM's anti-seawater corrosion and anti-ultraviolet properties, it is also widely used in marine environments for sealing doors, windows or decks of ships.

Other applications
Vibration and shock absorption: Highly elastic EPDM rubber can also be used as a vibration-proof material to reduce vibration damage to buildings or equipment.
Industrial pipeline sealing: Applied to the sealing of industrial pipeline joints to prevent leakage.
