Additive Masterbatch Plast Desiccant

Each type of additive masterbatch has some special properties to improve the end plastic product.

PLAST DESSICANT

Keep the polymer dry & stable despite humidity

PLAST DESSICANT -MB 101 PE is used to induce & sustain a state of dryness in its vicinity of Plastic substrate by absorbing moisture prevailing in raw material, filler, pigments and other sources. Most of the blown film extruded films often encounter defects such as fish eyes, dot problems , gassing, poor strength, bubble puncture, etc. Also Injection moulded components are found with silver streaks due to moisture.

Mechanism

A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity. Commonly used desiccants are solids that absorb water.Most prominently plastics films made with HDPE, LLDPE, LDPE and

other variety of Resins & additives in combination are found to have quality defects such as Fish eyes, dot problems , gassing, poor strength, bubble puncture are raised by moisture in Plastic film which could be solved through adding Dessicant Masterbatch. It is widely used for recycling Carry Bag,Tarpaulins, Agricultural Films & Multilayer films for Consumer and Industrial packaging.

Significance

Moisture in Plastic items can come through different types of raw materials, such as hygroscopic polymers, mineral fillers or pigments. Generally, recycled polymers often contain high levels of moisture. Several problems can occur when processing plastic materials with excess moisture such as

1. Degradation of the polymere

leading to a decrease in molecular weight, increased fluidity and decreased viscosity. Corrosion of the metal parts inside the extruder, shortening its shelf life.

2. Defects in the final product.

These defects can be both visual (fish eyes, puffs, holes, etc.) and/or functional (affectation of mechanical properties, variation in density, etc.). Desiccant MB reacts with the water molecules present in the polymer, binding them to its structure and then reduces or removes moisture immediately.

Key advantages of Bajaj Plast Dessicant

Significance

It’s an ideal solution for moisture removal / reduction without stopping the production process.

Recycling Process

Maintains the mechanical properties of the manufactured plastic items.

Reduction of Waste

Improves the surface properties of the manufactured article by eliminating streaks, fish eyes, density differences , holes, etc.

Ease of Processing

During recycling of polymers, it eliminates pre-drying processes as the moisture removal is done at zero cost: there is no energy consumption and no need to invest in drying machinery.
