ISOLENE® 40-S

ISOLENE® 40-S provides many performance properties in adhesive formulations and other compounds.

• Softens the resin
• Improves low-temperature tack
• Improves the resistance to bleed through
• Acts as an efficient vehicle for powdered additives and curatives into a rubber compound
• ISOLENE® liquid synthetic rubber cures by the same mechanism as polyisoprene rubber. It can replace rubber 1:1. A slight increase in curative levels may provide optimum performance when using levels above 15-20 phr of ISOLENE®.

ISOLENE® 40-S is ideal for pressure sensitive adhesive (PSA) formulations based on block copolymers. Typical applications include the following:

• Rubber and polymer processing aid.
• Reactive vehicle for powdered additives.
• Rheology modifier for lubricants.
• Polymer base for molding and tooling systems.
• Polymer base for electrical encapsulants.
• Production of pressure sensitive adhesives.
• UV curable polymers.

ISOLENE® 40-S is available in the following standard packages:

• 34 Lb. steel pail
• 350 Lb. steel drum

• ISOLENE® products are viscous polymers. Heating the drums lowers the viscosity for easier handling. Vent the drums before heating to avoid pressure build up.
• Avoid exposing ISOLENE® products to temperatures above 121°C (250°F). The polymer may form a skin and it may darken.
• ISOLENE® polymers can be compounded with virtually any type of rubber processing equipment. Processing requirements vary with the desired finished properties and with the other formulation ingredients

Store in a dry environment to prevent damage to the packaging. The liquid rubber products are stable over a wide temperature range. They are not damaged by freezing temperatures or occasional short-term exposure to temperatures of 66°C (150°F). The shelf life is a minimum of two years if stored properly in an unopened container.
