Technical Advantages

– Specifically designed for sealing strip materials such as rubber, EPDM, and TPV; delivers stronger and longer-lasting surface activation

– Integrated treatment structure ensures high uniformity, preventing localized over-treatment or insufficient activation

– Supports continuous in-line operation; matches the speed of sealing strip extrusion lines without disrupting production cycles

– Significantly enhances surface bonding performance; resolves delamination issues in flocking, gluing, and coating processes

– Preserves substrate elasticity and sealing integrity; does not alter the material’s physical properties

– Solvent-free, dry process; environmentally friendly with no wastewater or exhaust gas emissions

– High equipment stability allows for continuous, long-term mass production with easy maintenance.

– Compatible with sealing strips of various cross-sectional shapes; ensures comprehensive surface treatment with no untreated areas.

Solution

– Provides a comprehensive solution for professional plasma surface activation and polymerization treatment of rubber sealing strips.

– Resolves issues such as poor flock adhesion, coating detachment, and weak bonding caused by low surface energy, oil contamination, or mold release agents.

– Enhances interfacial bonding strength between the sealing strip and adhesives, coatings, flocking, or foam materials.

– Suitable for the pre-treatment of products such as automotive door and window seals, curtain wall seals, and home appliance seals.

– Enables integrated, in-line processing within extrusion production lines, improving product yield and durability.

– Meets the automotive and construction industries’ stringent standards for sealing strip adhesion and weather resistance.
