| Processing aids and waxes |
ˆ Top |
|
| » Acrylic processing aids are used in the processing of thermoplastics formulations. NichePlas offers the P-series of Processing Aids from Formosa Plastics Corporation for the processing of rigid PVC. These modify fusion behavior and can help optimize properties such as elongation at break and surface finish.
|
|
| » A range of synthetic waxes is available, sourced from Lion Chemtech Co Ltd in Korea. In all, 20 different grades are available. These are used in industries as diverse as plastics, rubbers, paints, inks, paper coating, hot melt adhesives and textiles. |

| Impact modifiers and toughening agents |
ˆ Top |
|
» MBS impact modifiers are used to improve the impact strength of rigid PVC at room or low temperatures. NichePlas offers a range of MBS modifiers from Formosa Plastics Corporation in Taiwan.
» The Narpow® powdered rubber range is used as a toughening agent for polymeric systems, such as thermoplastic and thermoset resins, rubbers and paint systems.
Narpow® rubbers are fully vulcanized and in the nano-size range (50-150nm, depending on grade). They have been developed by the SINOPEC Beijing Research Institute of Chemical Industry (BRICI) of China.
Narpow® has proven to be effective in the following applications:
•
|
To significantly improve properties such as impact strength, heat deflection temperature (HDT), glass transition temperature (Tg) and elongation at break when added to polymer systems. |
• |
As a nucleating agent for polyolefins. |
• |
In conjunction with nanoclays to balance properties with nanoclay composites. |
• |
In aqueous systems such as paints and coatings. |
•
|
To modify the mechanical properties of phenolic resin friction materials, including disc brake pads, drum brake linings and clutch facings. |

| Nanoclays |
ˆ Top |
|
» Cloisite® nanoclays are high aspect ratio additives for plastics based on montmorillonite clay. When dispersed in thermoplastic or thermosetting resins, Cloisite® provides the following performance advantage to the finished product:
• |
Increased modulus and strength; |
• |
Increased barrier properties to moisture, solvents, chemical vapours, gases such as O2 and flavours; |
• |
Reduced UV transmission; |
• |
Increase dimensional stability; |
• |
Good recycling properties; |
• |
Plastics will dye more easily; |
• |
Flame retardant properties; |
• |
The appearance of painted parts improves, and |
• |
Reduced static cling in films. |
Cloisite® nanoclays are produced by Southern Clay Products Inc of Texas, USA.

|
» The Luxilum™ range of Photoluminescent (Glow in the Dark) Pigments is available through Nite-Glo Innovations Pty Ltd, the holding company for NichePlas. These are quality, long-afterglow pigments, and achieve glow times of at least 12 hours after as little as 5 minutes light activation.

| Purging additives for process equipment |
ˆ Top |
|
| » NichePlas is Australasia’s major manufacturer and supplier of purging material, having acquired the PurgeX® business from Grange Products during 2009. |
|
| »PurgeX® is a mechanical purging agent that enables the safe, effective and efficient cleaning of plastics processing equipment. |
• |
Metal surfaces are cleaned using a unique scrubbing effect. The material is not abrasive to screw, barrel, die etc. |
• |
Particularly useful when changing colour, polymer, or when screw and barrel are carbonized. Enables rapid purging of the previous colour and/or polymer, so that machine downtime and loss of expensive polymer is minimized. |
• |
Suitable for injection moulding, extrusion and blow moulding processes. |
• |
Cost effective, as only a small amount is required, usually at 20% add rate to the polymer. |
|
|
| How PurgeX® works: |
|
| PurgeX® is a granular material that is blended in with a small amount of the polymer that you are using and fed into a starved screw/barrel.
The blended material is processed through your equipment at similar temperatures and revs to typical run conditions for the carrier polymer.
The PurgeX® material softens slightly, but does not melt, and thoroughly loosens carbonized and degraded resin, allowing the polymer to flush out the system.
This makes it particularly useful for: |
• |
Cleaning colour from your equipment |
• |
Cleaning polymer from your equipment |
• |
Removing carbon build-up and black specks |
• |
Regular preventative maintenance |
• |
Before manual cleaning |
|
|
| PurgeX® grades: |
|
• |
PurgeX® T for injection moulding (except where openings are less than 1.5mm) |
• |
PurgeX® S for extrusion, blow moulding, and injection moulding with openings less than 1.5mm |
• |
PurgeX® R for hot runner systems with a minimum clearance of 0.75mm |
