Handling and Health Safety

Molten polymers could be injured skin or eye so safety glasses and appropriate gloves are suggested to prevent possible thermal injuries. Also appropriate ventilation is suggested in working by melt polymer. Accumulation of fines or dust particles that are in this grade is not suitable because of explosion hazard probability. So adequated filters and grounding exists at all time are recommended.

Storage

Polyethylene products (in pelletised or powder form) should  not be stored in direct sunshine and/or heat radiation. Ultraviolet cause a change in the material properties.The Storage area should be dry and preferably don’t exceed 50 °C. Under cool, dry, dark conditions TSO Polymers polyolefin resins are expected to maintain the original material and processing properties for at least 18 month. TSO sould not ressponsible about quality diminishing such as color change, bad smell or ets which caused by bad storage conditions. It is better to process PE resin within 6 months after delivery.

Packaging

TSO Polymers Polyolefin resins are supplied in Pellet form packed in 25kg bags. Alternative packaging modes are avaliable for selected grades.

22501 is a LLDPE blown film grade designed for applications requiring good optical properties even at low extrusion
temperature. This resin combines ease of processing with low gels and it is well suited for blending with LDPE and for general purpose applications.
