LABEL STOCK ADHESIVES - UPM Raflatac
www.upmraflatac.comRubber-based adhesives are typically composed of a synthetic rubber, such as styrene butadiene rubber (SBR), styrene isoprene styrene (SIS) or natural rubber. Unlike acrylic polymers, rubber-based adhesives are not naturally tacky, so tackifiers must be added to give the base polymer those properties. Rubber-based adhesives

www.agilent.comStyrene-butadiene was identified as the copolymer in some of the PVC layers that were tested, with some variability in concentration between products (results not shown). Styrene-butadiene copolymers are often referred to as styrene-butadiene rubber (SBR) or styrene-butadiene-styrene (SBS). SBR is likely added to the PVC formulation to improve the

A BRIEF HISTORY OF RUBBER - OringsUSA
www.oringsusa.comThis was how GR-S, Buna S, Hycar OS and SBR appeared, which are styrene and butadiene copolymers. The launch-pad for the massive development of the synthetic rubber industry, this product could be vulcanized easily, and became the flagship of the world rubber industry, although its properties did not correspond to all the qualities of
TRUE TEST Allergen Info Sheets - SmartPractice
www.smartpractice.comUse rubber-free alternatives made of vinyl, plastic, leather, wood, or fabric. Some surgical gloves are labeled “hypoallergenic and rubber free” and are made of synthetic materials free of latex and all rubber accelerators. Examples are some gloves made of a synthetic co-polymer of styrene and butadiene, polyvinyl (PVC) or nitrile.

Urethanes 100-200 Wide variations in urethane chemistry applied to medical devices. *Elastomers: 1) Radiation tolerance is affected by the base polymer and the curing system used. Sulfur and resin cures are more durable. 2) All elastomers are subject to cross-linking.
