Tasnee LDPE 1925F
- Chemical Family
- PolyethylenesPolyolefins
Tasnee LD 1925F is a Low Density Polyethylene with a Melt Flow Rate of 2.0 g/10min (190°C/2.16 kg). Tasnee LD 1925F is mainly recommended for crosslinked and non-crosslinked foam applications. It designed to provide uniform cell distribution during LDPE foam extrusion process. Special additive package is used to control the foam cell structure so that uniform cell size and distribution occurred during foam extrusion process. It has a suitable molecular structure and special additive package for providing control and uniform foam cell structure and excellent mechanical properties to the foam. Tasnee LD 1925F can be easily processed on all types of LDPE foam extrusion equipment. The melt temperature is recommended to be in the range of 160 - 200°C.

- Storage Information
The material is packed in 25 kg bags or in bulk containers protecting it from contamination. Storage time of material longer than 6 months may have a negative influence on the quality of the final product. It is generally recommended to convert all materials latest within 6 months from delivery date. The material is subjected to degradation by ultra-violet radiation or by high storage temperatures. Therefore the material must be protected from direct sunlight, temperatures above 40°C and high atmospheric humidity during storage. Further unfavorable storage conditions are large fluctuations in ambient temperature and high atmospheric humidity. These conditions may lead to moisture condensing inside the packaging. Un der these circumstances, it is recommended to dry the material before use. TASNEE will not give any warranty to unfavorable storage conditions which may lead to quality deterioration such as color change, bad smell and inferior product performance.
- Recommended Applications
Base LDPE resin for crosslinked and non-crosslinked foam for packaging, heat and acoustic insulation, automotive applications, self-adhesive tapes etc.
- User Safety Recommendations
Workers should be protected from the possibility of skin or eye contact with molten polymer. As minimum precaution, safety glasses and heat resistance gloves are suggested to prevent mechanical or thermal injury to eyes and hands. Molten polymer exceeding processing condition requirements may degrade and release, fumes, vapors and unpleasant odor. In higher concentrations they may cause irritation of the mucus membranes. Fabrication areas should be ventilated to carry away fumes and vapors. Legislation on the control of emissions and pollution prevention must be observed. If the principles of sound manufacturing practice are adhered to and the place of work is well ventilated, no health hazards are involved in processing the material. The material may burn when supplied with excess heat and oxygen. It should be handled and stored away from contact with direct flames and/or ignition sources. In burning the material generates considerable heat and may release a dense black smoke. Fires should be extinguished by heavy foams or dry powder. For further information about safety in handling and processing please refer to the Material Safety Data Sheet (MSDS).
