Description
Introduction
Desicca works by irreversibly reacting with moisture as it converts to vapour and gas during processing — chemically binding with H₂O molecules to form stable compounds that stay stable at all plastic processing temperatures. The vapour and gas that would have damaged the finished product simply never form.
The result: cleaner film, fewer defects, higher production rate, and the ability to push more recycled material into your formulation without the quality compromise that usually follows.
Key Benefits
- Desicca reduces or eliminates moisture from recycled and reclaimed polymers, which is its core function.
- It reduces and prevents fish eye in extruded film, eliminating a visible defect.
- It reduces and prevents windows and lenses in films, delivering optical and thickness consistency.
- It removes porosity in molecular bonding, producing a stronger finished product at the molecular level.
- It allows increased addition levels of recycled material, acting as a direct cost-down lever for recycled feedstock processors.
- It addresses gassing in the barrel, supporting a higher production rate.
- It addresses surface defects and poor strength, improving finished product quality and performance.
- It addresses roughness and silver streaks, for cleaner finished film and moulded products.

FAQ
What is Desicca?
Desicca is a chemical desiccant that irreversibly reacts with moisture in recycled and reclaimed polymers. By chemically binding with H₂O molecules to form stable compounds, it prevents the formation of vapour and gas that would otherwise cause defects in finished products — fish eye, windows/lenses in films, porosity in molecular bonding, gassing in the barrel, roughness, and silver streaks.
How does Desicca work?
Desicca irreversibly reacts with moisture as it is in the process of conversion to vapour and gas. The reaction chemically binds the H₂O molecules to form stable compounds that remain stable at all plastic processing temperatures. This prevents the generation of vapour and gas that would otherwise damage the finished product.
Why is Desicca’s chemistry different from physical drying?
Physical drying (oven, hopper) removes moisture from the surface of polymer pellets only. Moisture trapped inside the polymer matrix remains. Desicca works wherever the moisture is — by chemically binding it at the molecular level before it can convert to vapour during processing.
What is the recommended dosage of Desicca?
For film extrusion: 1.5% to 2.5%. The exact dosage varies depending on the quality of the polymer being recycled.
Can Desicca help me use more recycled material in my formulation?
Yes. Desicca allows increased addition levels of recycled material — making it directly relevant to processors who want to push recycled content higher for cost or sustainability reasons.
Does Desicca eliminate fish eye in film?
Yes. Desicca addresses fish eye in extruded film by preventing the moisture-driven mechanism that causes it.
Does Desicca help with gassing in the extruder barrel?
Yes. By chemically binding moisture before it converts to vapour, Desicca prevents the gassing that causes lower output in the extruder.
Does Desicca remove porosity?
Yes. Desicca removes porosity in molecular bonding — addressing the structural weakness that moisture creates at the molecular level.
What plastic processing problems does Desicca solve?
Desicca addresses: surface defects, poor strength, fish eye in extruded film, gassing in barrel (which results in lower output), roughness, silver streaks, windows/lenses in films, and porosity in molecular bonding.
Is Desicca suitable for recycled polymer processing?
Yes — it’s specifically designed for recycled and reclaimed polymer processing where moisture in the feedstock can’t be reliably controlled.
Is Desicca manufactured in India?
Yes. Desicca is manufactured in India by Vin Group, an ISO 9001:2015 certified plastic and rubber additive manufacturer operating since 1997.
