Frequently asked questions

What is Desiccant Powder, and where is it used?

Plastic resins, especially recycled plastic, pick up moisture from the air. When melted, that moisture turns to steam inside the machine and ruins the final part with streaks, bubbles or holes. Desiccant Powder is mixed in beforehand to soak up the moisture, so the plastic melts cleanly without a separate drying stage. Used in recycled plastic, moisture-absorbing plastics, film and moulding lines, and factories without dryers.

What is Desiccant Masterbatch, and where is it used?

Same job as Desiccant Powder, but in pellet form. Drop these pellets into the machine alongside your regular plastic and they absorb moisture during melting, stopping steam defects and saving the drying step. Used in plastic film, bottle and container moulding, recycled plastic compounds, and lines without dryers.

What is Filler Masterbatch, and where is it used?

Virgin plastic is expensive. By blending in a cheaper mineral filler (chalk, talc or baking-soda-based) you can save 10 to 30 percent on material cost while tuning how stiff, dense or foamy the final part is. Filler Masterbatch comes as ready-made pellets that drop straight into your line. Used in woven bags and raffia, plastic film, moulded packaging, pipes and profiles, foamed parts, and sheet for thermoforming.

What is Colour Masterbatch, and where is it used?

To make plastic any specific colour, you would normally have to mix in raw pigments, messy and inconsistent batch to batch. Colour Masterbatch is pigment pre-mixed into plastic pellets at high concentration. Add a small amount to your base plastic and every batch comes out the exact same shade. Used in film and sheet, moulded parts, bottles and containers, pipes and profiles, and pre-coloured plastic compounds.

What is Additive Masterbatch, and where is it used?

Plastic parts often need extra properties: UV protection for outdoor use, anti-static for electronics packaging, slip for smooth film, fire resistance for cables. Each property comes as its own additive masterbatch, a single-purpose pellet you mix into your base plastic. Use one or stack several without changing your main recipe. Used in outdoor and farm sheets, electronics packaging, multi-layer film, cables and fire-safe plastic, recycled or smelly plastic, clear PP packaging, and metal packaging.
