Technical Details & Test Data

Example of Processing

Recommendable Screw Design:
(a) L/D of Extruder: 24 - 30
(b) Screw Design: Full - flight type is recommendable

Unnecessary mixing may generate gels

Too long feed-section cannot discharge the gas to air

(c) Compression Ratio: 3.0 - 3.5

Too small C.R. causes insufficient melting.
Too large C.R. causes excessive heat-generated.

(d) Plating

Chrome Plating ; Easy and Reasonable
Nickel Alloy Plating ; Flat Surface, but High Cost

Processing Temperature:

Compostability

BVE8049P is certified with the following regulation.

Safety & Health

Safety

BVE8049P is intended for indirect food contact only. Quality assurance and hygiene for cosmetics and pharmaceutical applications are not considered.
BVE8049P would be ignited by heat storage if BVE8049P is kept high temperature for a long time. When storing or disposing of the molded BVE8049P, please kindly cool it to 50 degree C or less.

Storage & Handling

Storage Information: Please kindly do not leave the bag of BVE8049P open for a long time. When storing after open, please seal the bag as soon as possible in order not to absorb moisture. High moisture content of BVE8049P may cause bubbling trouble during extrusion processes.
