Pentaerythritol Tetrastearate (commonly known as PETS) is a high-performance ester widely used in industrial manufacturing thanks to its exceptional lubrication, thermal stability, and processing-enhancing characteristics. This versatile compound supports smoother, more efficient production across a broad range of sectors — from plastics and rubber to coatings and metalworking.
In this blog, we'll explore the top 5 industrial applications and uses of PETS to help you understand why it's a critical additive for modern manufacturing.
1. Plastics & Polymer Processing
One of the primary uses of PETS is as a processing aid, internal and external lubricant, and mold release agent in plastics manufacturing. It significantly improves melt flow, reduces friction, and enhances processability during extrusion, injection molding, and calendering.
Advantages in plastics manufacturing:
- Reduces melt viscosity in polymers like PVC, PC, ABS, PET, and engineering plastics
- Minimizes thermal degradation and surface defects
- Enhances dimensional stability and surface gloss of finished parts
- Helps disperse fillers and additives uniformly
This makes PETS indispensable in producing automotive components, consumer goods, packaging materials, and precision engineered plastic articles.
2. Rubber & Elastomer Processing
In the rubber industry, PETS acts as a lubricant, processing stabilizer, and dispersing aid. During compounding and mixing, it reduces internal friction and helps fillers like carbon black or silica spread evenly throughout the rubber matrix.
Key benefits for rubber manufacturing:
- Improves flow and extrusion smoothness
- Reduces sticking to roll mills and molds
- Enhances surface finish and uniformity of molded rubber parts
- Increases production efficiency with less downtime
PETS is especially helpful in manufacturing synthetic rubber products like EPDM, SBR, and NBR, as well as rubber seals, hoses, and molded components.
3. Lubricants & Grease Additives
Thanks to its excellent anti-wear, thermal stability, and lubricity properties, PETS is a valuable additive in industrial and automotive lubricants and grease formulations. When blended into synthetic oils or greases, it forms a robust lubricating film on metal surfaces, reducing wear and energy loss under high stress and temperature conditions.
Benefits in lubricant applications:
- Reduces friction and machine wear
- Enhances oxidation and thermal stability
- Improves load-bearing properties
- Extends equipment and lubricant service life
This application makes PETS ideal for high-performance machinery, gear systems, engines, and heavy-duty industrial equipment.
4. Coatings, Paints & Printing Inks
PETS is also used as a flow modifier, dispersant, and surface improver in coatings, paints, and printing inks. It enhances pigment dispersion and promotes smooth film formation, which leads to improved aesthetics and durability in finished coatings.
Advantages in surface treatments:
- Promotes uniform pigment dispersion
- Enhances surface smoothness and gloss
- Reduces settling and caking in formulations
- Improves curing and flow properties
Applications include: industrial coatings, automotive finishes, powder coatings, and high-quality printing inks.
5. Paper, Textile & Specialty Coatings
Beyond plastics and coatings, PETS adds value in paper and textile processing by improving surface characteristics and process performance. In paper coatings, it helps provide smoothness, better printability, and durability, while in textile finishing it acts as a lubricant and handle improver.
Additional niche uses include:
- Enhancing film properties in coated papers
- Improving feel and friction properties in fabrics
- Supporting specialty coatings with better flow and surface quality
In these sectors, PETS contributes to elevated end-product performance and customer satisfaction.
