Synthetic Rubbers for Adhesives and Sealants

Oppanol® N PLUS by BASF is a polyisobutene-based binder for next-generation of electric vehicle (EV) batteries. It is designed for use in cathodes, anodes and electrolytes, where it reliably holds individual components together while keeping them effectively separated.

• It possesses high elasticity and extensibility to compensate for mechanical stress generated during charging and discharging.
• It is chemically inert, helps reduce unwanted side reactions, and supports battery stability and longer service life.
• Oppanol® N PLUS exhibits very narrow product specifications and consistent quality, enabling reduced process variability, lower reformulation requirements, decreased quality control efforts, and faster and stable process adjustments.

Resonac Chloroprene AF by Resonac (formerly Showa Denko) is a carboxylated chloroprene copolymer. It has a slow crystallization strength and milling normally is required for optimum solution quality. It provides the rapid bond strength development and the greatest hot bond strength.

• Excessive time and temperature of storage can cause a change in color and an increase in viscosity.
• It is primarily used in contact adhesives that require very high initial and ultimate bond strength and the ability to form bonds with minimum pressure over short open assembly periods.
• The compounded adhesives offer high cohesive strength derived from reaction with metal oxides.
• Resonac Chloroprene AF is used in demanding applications such as heat-formed high-pressure laminates and automotive trim attachments.

Resonac Chloroprene 671A by Resonac (formerly Showa Denko) is a high solid, anionic, aqueous dispersion of a high-gel chloroprene polymer. It offers a high wet gel strength and medium-slow crystallization rate. It has good storage stability, but pH decreases with time, and the rate depends on temperature and air exposure. The decrease is indicative of structural changes in the polymer and alterations in the colloidal properties of the latex. Resonac Chloroprene 671A is primarily used in dipped goods applications and is suitable for elastomer-based adhesives.
