PVA

PSB is a complex biological degradation of starch bentonite material in English shorthand, all written for the Pla-Starch Bentonite Material.

(1) Features
   Polyvinyl alcohol, also known as PVA, it is a recognized biodegradable materials. After the successful realization of our modified starch / bentonite / PVA prepared by melt intercalation composite material, processing all types of products, processing a variety of ways within the scope of 120 ℃ -200 ℃, such as blown film, extruded sheet, two-way drawing, injection molding, blow molding. Since PSB's products in addition to fully biodegradable, the biocompatibility, gloss, brightness, feel and heat resistance, and have different temperature water solubility, barrier properties, antistatic properties. Because of its wide range of uses, its price has a leading competitive advantage in a biodegradable grade material.
(2) Product testing degradation time
    Prepared in accordance with customer demand professional development, and ongoing EN13432 certification, the base polymer degradation performance appraisal, ISO14021 China Environmental Labeling Certification, FDA food packaging toxicological identification, GB15193 in food packaging and identification of physical and chemical testing the toxicity of various species.
(3) Product use
With PLA, PBS, PBAT, PPC and other bio-based materials blended to reduce costs, the effect of biodegradation.
(4) Applications
     Biaxially stretched film - tape machines, pearl film, matt film, anti-static film, shrink film, decorative materials for industrial use various types of packaging film composite film.
     Degradable film - electronics packaging, household appliances packaging, dust, rust-proof packaging, agricultural film, shopping bags, vests bags, paper bags, plastic bags, garbage bags, even the volume bags, tablecloths and other one-time environmental protection products.
     Injection products - children's toys, police barricades, post cards, and various one-time injection.
(5) Processing Equipment
     Special or general purpose film blowing machine, bag machines, printers, and other characteristics of products.

Product technology and methods of use

(1) try to choose a film blowing machine equipment, its aspect ratio: 28-32: 1, head compression ratio: 10: 1, die and mold cylinder diameter blow up ratio ≥1: 2.5, it is a good plasticizing improve product quality and increase product stability.
(2) The product can be directly blown PPVA, drawing, injection molding, foaming.
     This product PCB-XX (VA / PCBS / AT) can be directly blown film, drawing, injection molding, foaming。
(3) Product P-PVC pellets can be made of 0.01mm ~ 0.05mm biaxially stretched film.
     PSB-S pellets can be made of a biaxially stretched film of 0.015mm ~ 0.10mm.
     PSBC pellets may be blown 0.025mm ~ 0.10mm film.
     PSBC pellets were just blown out of the film due to the severe dehydration feel soft and brittle, low tensile strength, 24 hours, tensile strength, tear strength, elongation increased significantly, so just blown out of the film should put some time after processing bag.
     Blown printing step can be completed online PSB-C / PVA grade, without corona treatment.
