Weather resistance
This product is manufactured using high-performance EPDM rubber via a precision extrusion process and is specifically designed for the interface between the automotive windshield and the vehicle body. It offers excellent elasticity, resilience, and weather resistance, effectively filling assembly gaps to provide sealing, protection, and aesthetic enhancement. Widely used in the windshield installations of passenger cars, commercial vehicles, and specialty vehicles, it effectively prevents the ingress of rain, dust, and air while reducing wind noise and vibration, thereby improving overall vehicle comfort and visual quality.
Key Advantages:

Excellent sealing performance: Effectively blocks the ingress of rain, dust, and air.
Wind and noise reduction: Minimizes wind noise and unwanted sounds during driving.
High resilience: Maintains a stable seal even after prolonged compression.
Shock absorption and cushioning: Reduces vibration and impact between the glass and the vehicle body.
Weather and aging resistance: Resistant to ozone, UV radiation, and various outdoor environmental factors.
Temperature resistance: Withstands extreme cold, intense sunlight, and thermal cycling.
Enhanced aesthetics: Conceals gaps at the glass edges, creating a more attractive vehicle profile.
Dimensional stability: Produced via continuous extrusion with a uniform cross-section, making it ideal for mass production.

EPDM adhesive strips
As the "King of Weather Resistance," EPDM rubber strips are renowned for their superior resistance to ozone, ultraviolet radiation, and heat oxidation. They maintain excellent elasticity and compression recovery over a wide temperature range of -40℃ to 120℃. Widely used in fields requiring extremely high long-term outdoor durability, such as automotive door and window seals and building curtain wall seals, they are the preferred material for withstanding wind and sun exposure, with a service life of up to decades.

Colored and black compound rubber
As the "cornerstone of rubber product performance," compounded rubber is a key intermediate material formed by homogenizing raw rubber with various compounding agents through precise formulation and efficient mixing processes. It possesses highly customizable physicochemical properties. It provides a ready-to-use semi-finished product for subsequent molding processes such as calendering, extrusion, and compression molding, and is widely used in almost all rubber product fields, including automotive, construction, electronics, and medical industries. It is the core foundation that determines the quality and reliability of the final product.
