Technical Details & Test Data
- Rubber Mix Recipe and Measurement Conditions
Preparation of rubber mixes is carried out in accordance with ASTM D 3403 according to С method - on the roll mills prepared according to ASTM D 3182. Vulcanization characteristics are determined according to ASTM D 5289 using an MDR 2000 rheometer (flow meter).
Wait time for rubber mix before testing on rheometer is 2-6 hours.Parameter Standard Rubber mix recipe in parts by weight: - Rubber 100 - Zinc oxide 5 - IRB 7 (N330) carbon black 35.00 - Sulfur 2.25 - Stearic acid 2 - TBBS (N-tert-Butyl-2-benzothiazolesulfenamide) 0.70 Rheometer MDR 2000, measurement conditions: - Temperature, oС 160 - Duration, min 30 - Oscillation amplitude, deg. +/-0.5 - Oscillation frequency, Hz 1.7
Packaging & Availability
- Packing
Rubber briquettes (bales) are packaged in double-layer marked PE film (thickness of 0.05 +/- 0.01 mm, melting temperature of 108-110oС), then – in plastic box pallets of 540kg or in plywood or metal containers of 1,260kg.
- Transportation
Rubber is transported by all types of transport in covered transporting means in accordance to all rules of cargo’s transportation standing at transport of this form.
Storage & Handling
- Storage
Under normal conditions of storage (at a temperature not exceeding 30оС, in dry place free from direct sunlight)
- Guaranteed Shelf Life
2 (two) years from the manufacture date. After the expiration of the guaranteed shelf life, the rubber can be used for its intended purpose after confirmation of its conformity to the requirements of this product specification.
