Plastic functional masterbatch is an innovative material widely used in the production of plastic products. It has a variety of functions, including improving the strength of objects, increasing wear resistance, enhancing appearance, and protecting the environment. In this paper, we will discuss in depth the role, types and application areas of plastic functional masterbatch as well as the application of PFAS-free PPA processing aids on functional masterbatch, demonstrating the positive efforts of the plastics industry in sustainable development and environmental protection.

Definitions and roles

Plastic Functional Masterbatch is an additive which gives specific functions and properties to plastics by adding different substances to them. Plastic functional masterbatch enhances the mechanical strength of plastics, making them stronger and more durable. This is important in fields such as automotive, construction and aerospace, where there are stringent requirements for strength and durability of materials.

Plastic functional masterbatches can also improve the appearance of plastic products, increase the gloss and smoothness of the plastic surface, and enhance the grade of the product. It can also provide more functions for plastic products, such as UV protection, anti-static, flame retardant and so on. These functions make plastic products widely used in daily life and specific industries.

Types and areas of application

Plastic functional masterbatches can be categorized into various types, according to their different functions and applications. Below are a few common types of functional masterbatches and their applications:

1. Filler masterbatch: A filler masterbatch is a functional masterbatch in which fillers are added to plastics to increase stiffness and strength. One common filler is glass fiber, which can significantly increase the strength and stiffness of plastic products. Filler masterbatch is widely used in automobile parts, electronic product shells and other fields.

2. Calcium Carbonate Masterbatch: Calcium Carbonate Masterbatch is a multifunctional filler mainly used for reinforcing and improving the appearance of plastic products. As calcium carbonate is characterized by high strength and low cost, the use of calcium carbonate masterbatch can significantly reduce production costs. Calcium carbonate can also improve the heat resistance and weather resistance of plastic products, suitable for outdoor and high temperature environment.

3. Silicate Masterbatch: Silicate Masterbatch is a common appearance modifier used to improve the gloss and smoothness of plastic products. Silicate masterbatch has excellent abrasion and chemical resistance and can be used for lubrication and anti-adhesion of plastic products. It is widely used in household appliances, toys and furniture.

4. Nanomasterbatch: Nanomasterbatch is a kind of functional masterbatch prepared by using nanotechnology. Due to its tiny size and huge specific surface area, nanomasterbatch can significantly improve the mechanical properties, electrical conductivity and optical properties of plastic products. Nanomasterbatch has been widely used in electronics, optoelectronics and medical fields.

5. Anti-aging masterbatch: anti-aging masterbatch is compounded with light stabilizer, ultraviolet absorber, antioxidant and other additives, which can effectively inhibit or reduce the speed of thermal oxidation and photo-oxidation reaction of plastic macromolecules, and significantly improve the heat-resistant and light-resistant properties of plastic materials, slow down the degradation of the materials, the aging process, and prolong the service life of plastic products. Anti-aging masterbatch is widely used in plastic woven bags, container bags (FIBC), artificial lawn silk, plastic greenhouses, advertising road signs, light box advertising and other outdoor use products.

Plastic functional masterbatch is an important and innovative material which plays a key role in the production of plastic products. As an important masterbatch that can improve the quality of plastic products, plastic functional masterbatch will play a greater role in the future development. However, the functional masterbatch has always been in the processing of the need to face a variety of difficulties, such as processing poor fluidity, poor dispersion, etc., to solve the various types of functional masterbatch in the granulation process is a very critical step.

Processing difficulties that may be encountered by functional masterbatch in the process of granulation mainly include:

1. Dispersibility problem: the additives in the functional masterbatch need to be uniformly dispersed in the plastic substrate, and if they are not uniformly dispersed, the performance of the final product will be affected.

2. Particle size control: The size and distribution of the particle size will affect the compactness and processing performance of the mixture. Too small particle size may lead to adsorption agglomeration between particles and difficult to be dispersed in the plastic melt.

3. Hardness problem: Powdery particles with high hardness, such as ceramic powders and inorganic antimicrobial agents, may cause abrasion of the mixing equipment and affect the color and quality of the mixture.

4. Material build-up: During the production process, materials may build up at the discharge opening, which is usually caused by air entrapment in materials such as talcum powder.

5. Moisture absorption: Some components in the functional masterbatch may absorb moisture, resulting in bubbles or splashes during processing, affecting product quality.

PFAS-free PPA processing aids to solve functional masterbatch granulation problems: improve processing fluidity, improve mold mouth accumulation of material

SlLlMER series products are PFAS-free polymer processing aids (PPA) which were researched and developed by Chengdu Silike. This series of products is Pure modified Copolysiloxane, with properties of polysiloxane and the polar effect of the modified group, the products will migrate to the equipment surface, and work as a polymer processing aid(PPA). It is recommended to be diluted into a certain content masterbatch first, then used in polyolefin polymers, with a small addition, the melting flow, processability, and lubricity of the resin can effectively improved as well as eliminate meltfracture, greater wear resistance, smaller friction coefficient, extend equipment cleaning cycle, shorten downtime, and higher output and a better products surface, a perfect choice to replace pure fluorine-based PPA.
