POLYWAX™
The combination of controlled branching and low MW distribution and low melt point distribution inherent to the POLYWAX™ copolymers provides many attractive benefits for formulators.
Coatings
NuCera waxes are the key to coatings that go on smooth and last longer. You can count on the high purity and on-purpose production quality to enable the following in industrial, waterproofing, inks & can coatings:
- Linearity & high crystallinity for improved slip, high chemical resistance, and excellent heat stability.
- Higher Rub resistance for better appearance and easy cleanability in ink systems.
- Improved scratch resistance & reduced mar, along with a matting effect
- Products which are FDA indirect food contact approved
- More control for formulators due to well defined melt points
Product highlight: POLYWAXTM 655 & POLYWAX 655 T10
NuCera’s technology is unique in that it produces a narrow molecular weight polyethylene wax with NO branching.
Features & Benefits:
- Completely Linear
- Extremely Hard & Crystalline
- Narrow Melt Range
- Low Melt Viscosity

Plastics
NuCera polyethylene waxes and copolymers are a key component in plastic masterbatch, processing, mold release, and PP/PE/PS/EVA polymers. Applications and benefits include, but are not limited to:
- A lubricant and processing aide
- Improved metal release due to crystallinity
- Excellent heat resistance
- Reduced viscosity during processing
- Pigment dispersion
Product highlight: POLYWAXTM EP COPOLYMERS
NuCera’s copolymers are narrow molecular weight ethylene polymers with propylene branches => Controlled branching!
Features & Benefits (compared with POLYWAXTM waxes):
