Physical data in the above table is for reference only.

Vulcanization condition: 175℃× 5Min. Post-curing condition: 200℃ x 4h

Addition of curing agent: liquid 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane: 0.65%.

Advantage:

- Flexible processability

- High tear strength

- Good yellowing resistance

Applications:

- High-tear-strength molded products, such as complicated bakeware and cell-phone cover

Packing & Storage:

- 20kg/ carton lined with plastic bags or sheets.

- The products have a shelf life of 9 months from date of manufacture depending on the shore hardness if stored at room temperature in the originally sealed container.
