PVDC Resin
Product Name：
PVDC Resin SLV22
Product Application：
SLV22 is a PVDC resin copolymer of vinylidene chloride and vinyl chloride (VDC/VC).
It can be blown into monolaver films through the "double bubble" process for biaxial orientation. The Extrusion resin can be blended with additives such as processing aids to extrude into thickness of 10-12 um cling films. These films are widely used in household application.
Packaging, storage and transportation:
It should be lightly loaded and unloaded during transportation. It is strictly prohibited to prevent collision, avoid rain, exposure and pollution. The product should be stored in a ventilated, dry and clean warehouse, and heavy pressure is strictly prohibited.
Typical Product Property Data:
Typical properties: these are not to be construed as specifications.
The above data is based on PVDC cling films made of SLV22 grade resin, and the film is about 12 um in thickness.
Processing:
SLV20 is a kind of heat sensitive resin and will be carbonized if residence time takes too long in the extruder machine. Thermal degradation during melt processing will release hydrogen chloride (HCl) gas. lf the resinsare affected with damp, the bubble will be broken and the yield rate will be much lower. The normal processing period will exceed 7 days, if the nomal temperature is set in the qualified machine.
It is essential that:
(1) Regarding construction materials for the machine, we recommend thatthe parts in contact with the meltPVDC have high corrosion resistance and contain no catalytic materials, i.e. those made of high Ni alloys;
(2) The residence time is minimized.
