Overview
We have developed five commonly used products in the EVA series. This product is made of highly elastic material and can replace styrofoam and rubber rings. Compared to styrofoam and rubber rings, it has a very high cost performance and resilience comparable to styrofoam. It can be used for products that are repeatedly opened and reused, and has strong chemical compatibility. Due to its compatibility with styrofoam and rubber rings, it can also be used for food contact products.
TECHNICAL DATE SHEET
Product Name: ③EVA food grade high elastic material
PRODUCTION DATE: September 2023
| ITEMS | |
| Density | 150±5 kg/m³ |
| Shaw C hardness | 45-50° |
| Tensile strength | 1.9Mpa |
| Elongation at break | ≥210% |
| Main components | EVA\LDPE\CACO3 |
| Immersion test | No chemical reaction with MEK
Toluene immersion is insoluble and has no chemical reaction, with slight swelling. After air drying, the shrinkage rate is small (chemical properties are better than rubber rings) |
| Storage time | 3 years (no sunlight exposure) |
