Uses of PET/Polyester Masterbatch in Polymer Processing

Polyethylene Terephthalate is a common material in the polyester family. That has got abuzz in the plastic processing world due to its recyclability of products. Thus, the polymer has support from environment concern users and companies worldwide.

The common uses of PET are to make packaging application owing to its clarity, strength and lightweight properties. However, PET processors face numerous challenges in producing superior products. The standard issues that come in the PET products are high surface friction after processing, poor mould release, issues with flow lines, scratching and less packing density.

However, processors can avoid these problems using a special additive during the manufacturing process. As a result, companies can produce superior products as demand by consumers in the market. That is possible with the use of PET/Polyester masterbatch during manufacturing in the plant. The masterbatch has applications beyond increasing the processability of PET products.

Key benefits of using PET masterbatch:

• Up to 60% reduction in surface friction and mould release.
• Up to 25% increase in packing density performance.
• Enhance packaging and processability of moulded parts.
• Increase the flow of line in PET processing.
• Easy to process with reduced noises in manufacturing.
• Leaves no adverse on the physical properties.
• Save costs in process as low energy is required in extrusion.

Significance of PET masterbatch in plastic processing

Like other additives, PET masterbatch has many applications in the polymer processing industry. Here are common uses of this additive:

Colour and Clarity

One of the primary purposes of using a masterbatch is to add colour to the base polymer. So, this masterbatch adds the desired colour and maintain clarity of PET products after processing. The colour remains unaltered after adding this masterbatch on the product.

Anti-scratch property

The anti-scratch property is a need in many plastic products. It helps to preserve the look, surface quality and feel for consumers in the market. The masterbatch helps to increase scratch resistance on processing by lowering scratch visibility and whitening in automotive accessories and other products. Further, it reduces the friction on the surface during manufacturing.

Improved mould release

The masterbatch also helps to enhance mould release on the products. However, the addition level and recommendation products will depend on polymers and applications. Polymer additive experts are needed to find a compatible solution for this problem.

Anti-fog

Fogging is a condition in the polymer process where small water droplets form on the surface of transparent film. The fog occurs when there is a difference in inside and outside temperature.

However, this problem can duly be solved by using an anti-fogging additive in the processing. Utilizing the additive, it reduces the surface tension between the layer of the water surface. It also improves light transmission and transparency of agricultural and food packaging products.

There are separate masterbatches for PET and polyester polymers in the industry. A processor needs to choose compatible additive to get the desired outcome and features in products. Apart from this additive, the wax base pigment dispersion PVC is getting popular to produce PET and PVC products in the industry.

Conclusion

PET products will get popular in the coming days due to their recyclability. However, plastic processors must buy standard masterbatch, suiting the demand of their consumers.
