Polymer modifiers > for flowability improvement in plastics applications

BTC offers various technologies to adjust the flowability of plastics. They influence the flowability and melt viscosity of plastics by either morphologic changes (accelothene® for predominately polyolefins) selective scission of the polymer chains (Irgatec® for predominately polypropylene), or chain extension and branching of polymers (Joncryl® ADR for predominately engineering plastics).

With the new additive accelothene® BTC is broadening its product range for the plastics industry. accelothene® is predominantly used in the polyolefin processing industry for injection moulding, extrusion and blow moulding. accelothene® enhances the injection moulding process, allowing the processing temperature to be reduced. This enables manufacturers of plastic goods to significantly cut the cooling time and to shorten the total cycle time. This in turn leads to energy savings and at the same time increased production capacity. Furthermore, the lower processing temperature reduces internal stress, resulting in improved end-use properties such as impact resistance.

Properties of polymer modifiers for flowability improvement

accelothene® is an innovative polyolefin composition, which allows a co-crystallisation with the base polymer that is injected. This provides the great advantage of no negative impacts on the mechanical performance of the product. accelothene® is delivered as colourless pellets and is added to the base polymer with standard dosage equipment. Irgatec® CR 76 A is a peroxide-free viscosity-breaking technology, yielding a better processing and design flexibility of hygiene nonwovens, improved mechanical properties and a broadened bonding window of spunbond nonwoven. It also allows the recycling of nonwoven waste into high quality nonwovens. It offers flexibility in product design by optimizing process parameters. 
Joncryl® products act as either chain extenders or flow modifiers.

Applications of polymer modifiers for flowability improvement

accelothene® enhances the injection moulding process, which enables manufacturers of plastic goods

  • to reduce the processing temperature,
  • to significantly cut the cooling time,
  • to shorten the total cycle time by up to 25%. 

This in turn leads to

  • energy savings,
  • and at the same time increased production capacity.

Furthermore, the lower processing temperature reduces internal stress, resulting in improved end-use properties such as impact resistance. 

Irgatec® CR 76 A is designed for the manufacture of polypropylene based non-woven applications.

The Joncyl® ADR product range is used in plastics applications for the recycling of PET, PET strapping, fibers and as compatibilizers. Joncyl® ADR products increase the recyclability; they improve the mechanical properties as well as the compatibility between fillers and various thermoplastic resins.
