It’s a Type 250 stem density polyolefin fastener that is backed with a rubber based pressure sensitive adhesive. Our fastener has a closure action life of 1000 times before losing 50% of its original tensile strength, making it reliable for longer. This product has low temperature performance, with a temperature resistance of up to +50 °C long-term (+70 °C short-term), and is for indoor use only.
