NBR Foam Grip for Seal Strip Soft Flexible Custom Size

Product Description

NBR Foam — Built for Where Standard Foams Fail

NBR foam combines closed-cell waterproofing, self-extinguishing fire behavior, and natural oil resistance in one material. It rebounds instantly after compression, performs reliably from -40°C to +105°C, and lasts over a decade without cracking or degrading. Factory-direct from our Dongguan production line, fully customizable in density, size, and adhesive — consistent quality, no middlemen.

Specification

NBR Foam — Material Advantages

1.Closed-cell structure — over 95% closed-cell rate. Water, moisture, and condensation cannot penetrate. No additional waterproof coating required.
2.Self-extinguishing — stops burning immediately when the flame source is removed. No dripping, no flame spread.
3.Natural oil and chemical resistance — nitrile rubber base resists oils, fuels, solvents, and mild chemicals without swelling or degrading.
4.High elasticity and instant recovery — compresses under impact and rebounds to original shape within seconds. No permanent deformation even after repeated loading.
5.Wide temperature tolerance — performs reliably from -40°C to +105°C. Remains flexible in freezing conditions, stable under high heat.
6.Excellent aging and weather resistance — resists UV exposure, ozone cracking, and general weathering. Service life exceeds 10 years under normal conditions.
7.Lightweight with high tensile strength — low density for easy handling, yet strong enough to withstand tearing, stretching, and repeated impact.
8.Non-toxic and environmentally compliant — ROHS and REACH compliant. Safe for indoor use, food processing areas, and regulated export markets.
9.One-piece molded, no glue layers — seamless construction means no delamination, no peeling, and consistent performance across the entire product.
