filler masterbatch and its applications

Classifications of Filler Masterbatch

Traditionally, most fillers were considered as a child category of additives because they affect nothing or even decrease the strength of the polymer. Their main usage purpose is reducing the cost of input materials by replacing expensive polymers. Besides, they probably fasten molding cycles. Other plastic properties could be changed, depending on which type of […]

Design of Plastic Products (part 2): The holistic design approach

The part becomes more rigid as it cools in the mold. Even an essentially rigid material might be successfully ejected from the mold if this function is performed while the part is still soft.  However, the part must also be rigid enough to withstand the force of ejection without enduring permanent distortion. The point at […]

Design of Plastic Products (part 1): The holistic design approach

There are 4 principle elements to a successful plastic product: material selection, part design, tooling, and processing. Typically, product designers are effective part designers but have limited background in the other disciplines.  This leads to products which are more expensive than necessary and difficult to manufacture—which also increases the cost.  Many companies have solved this […]

Antioxidants: What are primary and secondary antioxidants?

Antioxidants are used in a variety of resins to prevent oxidative degradation. Degradation is initiated by the action of highly reactive free radicals caused by heat, radiation, mechanical shear, or metallic impurities. The initiation of free radicals may occur during polymerization, processing, or fabrication. Once the first step of initiation occurs, propagation follows. Propagation is […]

Anti-blocking and Slip agent: 4 selecting criteria

Anti-blocking agents roughen the surface of the film to create a spacing effect.  Self-adhesion is an undesirable situation when using LLDPE and LDPE film. Anti-blocking additives like other plastic raw materials are melted into the thermoplastics directly or in use of a masterbatch. Therefore, an anti-blocking additive is developed to make a slight surface roughness. […]

Flame retardant additives: Essential safety materials (2020)

Flame retardants are in a unique position among plastics additives in that they are both created by regulations and yet are threatened by other regulations. They are expensive and lower the physical properties of the plastics in which they are employed.  On the other hand, environmental and toxicity concerns now have regulators looking at the […]
