Product Overview

This self-adhesive EVA foam strip is made from quality foamed EVA with 3M 9448A high-performance double-sided tape on the back, combining waterproof sealing, cushioning, shock absorption and noise reduction in a single product. It is widely used for door and window sealing, wardrobe dust protection, automotive interiors and electronics cushioning — an ideal sealing solution for both industrial and household use.

Core Advantages

3M 9448A double-sided tape: uses the internationally recognised 3M 9448A non-woven double-sided tape with strong initial tack and lasting holding power, service temperature from -20 °C to 120 °C, ensuring stable bonding in all kinds of environments — it will not fall off or leave residue.

Quality EVA foam substrate: high-density foamed EVA, soft and resilient with excellent compression set resistance. Its closed-cell structure blocks water vapour penetration for outstanding waterproof and moisture-proof performance.

Precision slitting: precision slitting equipment holds width tolerance within ±0.5 mm with uniform thickness, ensuring dimensional accuracy and clean appearance on every strip.

Product Characteristics

Waterproof sealing: the closed-cell EVA structure blocks water and air penetration, suitable for outdoor doors, windows and bathroom cabinets in humid environments.

Cushioning and shock absorption: the soft EVA foam absorbs impact and vibration, protecting doors, windows and furniture from collision damage while reducing noise when opening and closing.

Weather resistance: service range -20 °C to 120 °C, UV- and ageing-resistant; it will not harden or crack during long-term indoor or outdoor use.

Easy installation: peel off the release liner and apply — no extra tools or glue needed. DIY installation is simple and efficient, saving installation time.

Custom production: thickness (1 mm–20 mm), width (5 mm–200 mm), length and colour can all be customized to suit different applications.
