Desiccant Masterbatch

Desiccant Masterbatches (Moisture Absorbent Masterbatches)

As the name suggests, a desiccant masterbatch is an advanced functional masterbatch developed to solve the moisture problem. A desiccant is a substance designed to eliminate humidity and enhance extrusion and injection processes. A desiccant masterbatch gives a complete solution to the processor so as to reduce or remove undesired moisture.

 

Moisture can be present in raw materials such as hygroscopic polymers, fillers, and pigments.

This masterbatch is used in eliminating moisture in virgin and recycled LD, LLDPE, HM, PP etc.

Desiccant masterbatch is suitable for blown film extrusion, injection molding, and blow molding process. It is used directly by mixing the masterbatch and the damp plastic material uniformly.

 

Moisture Absorber Masterbatches are provided in granular or pellet form with a high concentration of active agents and excellent dispersion into the end product. Benefits of using this product include avoiding problems during the process such as :  fisheyes, holes, and grooves

Why Use Desiccant Masterbatches?

• Desiccant masterbatches can counter problems that develop during the processing of plastics due to the presence of moisture and prevent adsorption of moisture during transportation.
• Moisture can be present in raw materials such as hygroscopic polymers, fillers, and pigments.
• Reprocess polymer can also have high moisture content. When processing polymer with high moisture content the polymer can become porous and show voids/lower tensile in the final articles or extruded/blown sheet. In film applications, the high moisture content can lead to film bubble breakage.

What is the Mechanism of Action of Desiccant Masterbatches?

Desiccant masterbatch chemically binds moisture during processing and allows higher levels of reprocessing polymers & fillers to be used.

Desiccant Masterbatches help to reduce:

• Fish Eyes.
• Windows/lenses in films.
• Silver streak in molding.

Desiccant Masterbatches has the following advantages:

• Increases filler addition level.
• Maintain Strength.
• Solves moisture-derived technical problems: fish eye, holes, streaks, surface defects, etc.
• Improves mechanical properties.
• Eliminates moisture problems due to the use of additives/pigments.
• Reduces metal corrosion problems in the extruder.
• Eliminates the drying process for hygroscopic polymers.
• Energy consumption = 0.
• No investment in drying machinery.
• No plant space was taken up.
• High absorbent power.
• Immediately solves a moisture problem without having to stop production.
• Eliminates the need to dry the waste for reuse.

 

Applications of Desiccant Masterbatches (Moisture Absorbent Masterbatches)

• Handle of plastic bags
• Agricultural plastic film
• Paper like plastic forms.
• Bin bags.
• Recycled polymers processing
• Barrels and drums
• Processing of woven sacks
• Injection processes.
• Twin wall sheets.
• Thermoformed sheets.
• Corrugated pipes.

 

 

Why Use Pure Polymers Desiccant Masterbatches?

Pure Polymers Desiccant Masterbatches are highly recommended for the use as additives for the transformation of recycled polymers (especially post-consumption materials), but also for virgin polymers (storage problems, or hygroscopic polymers) that require a prior slow/costly drying process.

 

Pure Polymers Desiccant Masterbatches concentrate bind moisture during the processing of plastic materials. The active ingredient in these masterbatches reacts chemically with water molecules and effectively removes them from the system.  Desiccant masterbatches may be effective for products produced with hygroscopic materials where lensing (fish eyes) can be a problem.  Moisture absorbing masterbatches are useful to reduce lensing after storage of raw materials in high humidity areas.  Concentrates containing a desiccant may be able to bind up to 20% of the masterbatch weight; but in practice, the binding ability will be lower.

RECOMMENDED DOSAGE:

Average dosage 1-3%.

STORAGE & HANDLING:

Product is highly hydroscopic. Use over within 16-24 hours after opening the packing. Keep original packaging close.

Pre drying of Desiccant masterbatch may be required. Avoid overheating. Packaging: 5 Kg bags.

Special Features:

• Increases the value of plastic.
• Prevents or reduces moisture.
• Improves quality.
• Cost-effective and economical.
• Environmentally safe and non-toxic.

 

PE Masterbatch of Desiccant (DES01)

 

Get rid of moisture in HDPE/LLDPE/LDPE plastics and starch-based biomaterials.

 

Replace the drying equipment, stop this drying procedure, reduce the cost of power, and reduce production costs.

 

Mix masterbatch PE desiccant (granule) with HDPE/LDPE/LLDPE (granule).

 

 

• If you weigh LDPE/LLDPE/HDPE pellets both before as well after drying there will be a weight loss will be certain. If you employ PE desiccant masterbatch there is no loss of weight. Weight loss is one of the aspects of expense.
• No toxins, absolutely harmless Environmentally friendly.
• The pellets of LDPE/LLDPE/HDPE are recycled or re water, thereby converting biodegradable plastics.
• Plastic desiccant masterbatch named as desiccant compound, desiccant additive, desiccants agent, desiccants composite, plastic desiccant masterbatch, desiccant additive, desiccants agent.

Product Description

• The recycled Polythene as well as recycled Polypropylene frequently contain trace moisture. If not removed the moisture, it will develop into bubbles or drain marks in the surfaces of associated products after processing.
• The masterbatch made of plastic desiccant is a brand new kind of functional masterbatch specially created to remove water content in the recycling of the PE as well as PP. The masterbatch can be used to mix in the raw materials prior to plastic molding process, which is used to make the drying process easier making it easy to use. It will increase the efficiency of production and cut down on energy usage.

Applications

• It is widely used in PE as well as PP recycling materials, as well as in the wetting plastics for the blowing process and for injection.
• A wide range of applications for PE as well as PP recycling materials as well as the wetting plastic that has the highest demands for blowing, injection and sheeting.

 

Validity

Valid for 8 to 84 hours if exposed to open air. Shelf time is between 6 and 12 months after the date of production if it is well packed.

Based on the weather and the environment the reference value could alter based on the weather and environment.
The sooner you can use it the earlier, the sooner.

After exposure to the open air, you can begin production as soon as possible the earlier, the more effective.
If the product is unfit (pellet completely white from the surface to the center) do don’t use it.

Repack the bag immediately after taking it out of the bag.
Storage should be in a dry location with good ventilation. Protect from the sun and rain.
