PP filler masterbatch is a combination of high-quality polypropylene resin and calcium carbonate. PP fillers are widely produced and used in the plastic industry thanks to their excellent cost-effectiveness as well as inheriting the outstanding advantages of traditional plastics such as tensile strength, and flexibility,...
Compared with traditional plastic, filler masterbatch is a new material, born first with the goal of solving the problem of input materials for businesses. Accordingly, despite achieving an impressive growth rate of 15-20%/year within 10 years (2009 - 2019), Vietnam's plastic industry still faces a difficult problem called input materials. According to statistics, each year the plastic industry needs an average of 2-2.5 million tons of raw materials, but 75-80% of them are imported.
Vietnam's plastic industry depends largely on foreign raw materials. This has placed a huge burden on domestic enterprises because the cost of input materials accounts for 60-70% of the product cost. Importing raw materials not only increases production costs and reduces competitiveness but also makes it difficult for us to take advantage of tax incentives due to constraints on rules of origin and the inability to source raw materials.
As a result, filler masterbatch was born, becoming an effective solution to help businesses solve the problem of raw materials, in which the highlight is PP filler masterbatch.
What is PP filler masterbatch? Why do we use it?
Polypropylene (PP) is the most widely used thermoplastic on the market today. With outstanding properties such as good elasticity, anti-deformation, electrical insulation, and especially high transparency, polypropylene is especially used in the packaging industry, and manufacturing household appliances, requiring high aesthetics and durability.
Accordingly, PP filler masterbatch is a combination of high-quality polypropylene (PP) and calcium carbonate (CaCO3) resins (75-80%). Calcium carbonate is a familiar element that makes up the shells of many organisms such as seashells, clams, corals, etc. This material exists in large reserves in the form of thousand-year-old limestone mountains in the North of Vietnam.
Using calcium carbonate to replace a part of virgin resin can reduce the production costs for businesses (calcium carbonate is an available resource in Vietnam), and completely eliminate additional costs or risks in international transactions. On the other hand, calcium carbonate has a very high melting point (up to 825 degrees Celsius), is non-flammable, has good hardness and high brightness. Therefore, using PP filler helps to improve hardness, and impact resistance, increase heat resistance as well as make the products more transparent.
Caution:1. Non-woven fabrics
Non-woven fabrics are one of the most prominent applications of PP plastic fillers. The product is made from uncoated, high-fine calcium carbonate powder combined with polypropylene resin and other processing additives. Using PP filler masterbatch for non-woven fabric both ensures high breaking strength and improves the elongation of the product.2. Spinning, weaving
The most important indicator of a jumbo bag is its load capacity. This index is measured by the breaking force and elongation of the yarn. Technically, the tensile strength and elongation of the yarn are determined by the proportion of virgin polypropylene resin in the input material. The higher this ratio, the higher the load capacity of the bag. However, using a large percentage of resin means increasing product costs. Therefore, in order to reduce costs, PP filler is an appropriate choice because it ensures the load-carrying capacity of the bag without affecting the product inside (unlike when using recycled plastic).
3. Extrusion, blown film, injection molding
PP filler is also widely used in extrusion, blow film, and injection molding products. The material has the ability to cool faster, thereby increasing extruder productivity, and saving time. Besides, PP fillers also improve the mechanical properties of the finished product, reduce shrinkage, increase hardness and transparency, and most importantly, reduce production costs for businesses.
