Storage & Handling
- Shelf Life
- 2 years
- Handling
- 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. 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.
- Storage Condition
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.
