Notes on the production of synthetic rubber

Notes on the production of synthetic rubber Single recovery The quality of the rubber and the rate of the reaction both decrease with the polymer advancement, so it is customary to stop the reaction before complete conversion. Unreacted monolayer recovery and purification is an essential step in the synthetic rubber production unit. Recovery methods are used by leachate vaporization or […]

What are the Materials and Methods for footwear industry?

The NR (STR5L) rubber was purchased in block form from Chana Latex Co., Ltd. (Songkhla, Thailand), whereas CB (N-330, particles size 30 nm) and china clay (CC, C-400, mesh size 400) were acquired from GSP Products Co., Ltd. (Bangkok, Thailand). The CB and CC are generally considered as reinforcement and non-reinforcement fillers, respectively. Paraffinic oil (PO, grade A no.15), added […]

What are the structures and properties of SBR?

What are the structures and properties of SBR?

Synthetic rubber Styrene butadiene rubber While most of the properties of SBR are comparable with NR, but in some respects like heat build-up, tack and gum tensile strength make it inferior to natural rubber. Other disadvantages include: Low elongation at break Low hot tear strength Hysteresis, resilience . But the addition of resins and reinforcing fillers adequately improve these properties. […]
