Product Highlights

In an ever demanding world where there are increasing pressures on cost reduction, component weight saving and improving production rates. These challenges can in certain applications be met by incorporating a blowing agent.

With the endothermic blowing agents, as part of their functionality, they will absorb heat energy from their surroundings. This, in injection molding, lends itself ideally to reducing in mold cooling times and gives the processor the ability to dramatically reduce mold cycle times.

Details

Wells Plastics blowing agent masterbatches contain specialist active ingredients that are designed to decompose at a specific given temperature, evolving gasses such as nitrogen (N₂) or carbon dioxide (CO₂). The evolved gasses will impart a cellular structure to the polymer, making the finished part lighter in weight and also using less polymer to fill the mold volume. Total conversion of the additive to gas within the user’s process is critical for ensuring that the maximum cost reduction benefit is achieved.

Blowing agents are widely used to achieve weight reduction and polymer saving in injection molding e.g. automotive parts, plastic pallets and crates. Blowing agents may also be used to produce foamed insulation materials and to reduce sink marks in molding applications.

Wells Plastics blowing agents are designed to deliver controlled, uniform cell structures, providing the processor with batch to batch reproducibility. Both endothermic and exothermic blowing agent masterbatches are available from Wells Plastics.

Wells Plastics blowing agent masterbatches can be custom formulated to suit specific applications or polymer types. Please contact your Wells Plastics representative for further details.
