LIWEI CE 35
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
LIWEI CE 35 is an aqueous dispersion of a terpolymer of vinyl chloride, vinyl acetate and ethylene.
[Properties]
• LIWEI CE 35 is a stiff film-former and imparts excellent heat-sealability and high frequency (HF)-weldability to nonwovens & textiles substrates.
• Because of its high chlorine content, LIWEI CE 35 can be used in conjunction with antimony oxide, phosphorous nitrogen compounds or other flame-retardant additives to produce flame retardant coatings.
• It also especially suitable for making plasticizer-free heat sealable and high frequency weldable coatings on paper and cardboard.

[Storage]
When the dispersion is stored in tanks, proper storage conditions must be maintained. The product has a shelf life of 6 months starting from the date of receipt if stored in the original, unopened containers at temperatures between 5 and 30 °C. Any longer periods for the maximum storage period that may be described in the Certificate of Analysis which accompanies each shipment of the product, take preference over this suggestion in which case the time period stated in the Certificate of Analysis shall be solely authoritative. Iron or galvanized iron containers and equipment are not recommended. Corrosion could result in discoloration of the dispersion or blends made from it in further processing. We therefore recommend the use of containers and equipment made of ceramic, rubberized or enameled materials,appropriately finished stainless steel, or plastic (rigid PVC, polyethylene or polyester resin). As polymer dispersions may tend to superficial film formation, skins or lumps may be formed during storage or transportation. A filtration process is thus recommended prior to utilization of the product.
