Preciprocal-grain use instructions: Different processing temperature requirements for actual production equipment, and the amount of color masterbatch should be controlled at 0.8% to 5% to ensure a smooth process.

Polypropylene staple fiber parent product quality indicators:

Appearance: uniform color, no dust;

Particle size: φ (2.7 ~ 3.3) mm × (3 ~ 3.4) mm

Water: ≤0.3% (wt.)

Color difference: 4 (gray card)

Heat resistance: ≥ 240 ° C (applied to BCF, the type heat resistance of the meltblown non-woven fabric is relatively high)

Polypropylene staple fiber puzzle package storage:

      The products are double-layer packaging, the inner layer is a waterproof and moisture-proof polyethylene film bag, and the outer layer is a paper-plastic composite bag. Standard packaging 25 kg / bag. Please be stored in a ventilated, dry place, down the pad, avoid sun, rain, and master-bombs color shelf life of 5 years. After the use of the open package, the remainder should be reopened, prevent dust from pollution and moisture.

      

The polypropylene staple fiber granules can make the pigment uniformly dispersed in the article, so that the pigment is good compatible with the resin. Solved the product direct pigment dyeing, pigments and trees, uneven dyeing, contaminated equipment and other products.

The color masterbatch is convenient, since the color masterbatch is similar to the particle size of the plastic particles, the specific gravity is comparable, the mixture is good, and the method of mixing, or even manual stirring can be used, can be fully mixed, or a set of placing coextrusion Methods.
