Anti-Shrinkage Masterbatch: Dimensional Stability for Precision Plastics
In the plastic molding and extrusion industry, maintaining dimensional accuracy is critical—especially in technical, automotive, appliance, and packaging applications. One of the most common issues that affects plastic components post-processing is shrinkage, which can cause warping, size mismatch, cracks, and rejections.
The solution? Anti-Shrinkage Masterbatch—a specialized additive masterbatch designed to reduce shrinkage and improve the structural integrity of molded or extruded plastic parts.
What is Anti-Shrinkage Masterbatch?
Anti-Shrinkage Masterbatch (sometimes referred to as Anti-Skrinage Masterbatch) is a concentrated formulation of mineral fillers (like talc, calcium carbonate, or glass beads) and anti-warping agents that are dispersed in a compatible polymer carrier.
It is added to thermoplastics during processing to:
- Minimize post-cooling shrinkage
- Prevent warping and deformation
- Enhance mechanical stability and dimensional control
Available for a wide range of base resins, such as:
- PP (Polypropylene)
- PE (Polyethylene)
- ABS
- HIPS
- PA (Nylon)
- PBT
- PET
- PC and blends
Technical Overview
| Property | Typical Range |
| Carrier Resin | PP, PE, ABS, universal |
| Dosage Level | 5% – 25% (depending on application) |
| Filler Type | Talc, Calcium Carbonate, Silica, etc. |
| Particle Size | Micronized or nano-grade options |
| Thermal Stability | Up to 300°C |
| Surface Finish Impact | Matte to semi-gloss (can be customized) |
How It Works
Shrinkage occurs when a plastic part cools and solidifies, leading to contraction of polymer chains. Anti-shrinkage masterbatch works by:
- Incorporating inorganic fillers that occupy volume and resist shrinkage.
- Slowing down crystallization (in semi-crystalline polymers like PP).
- Improving heat dissipation, resulting in more uniform cooling.
Conclusion
Anti-Shrinkage Masterbatch is an essential additive for manufacturers seeking precision, stability, and zero-warp performance in plastic parts. From automotive trims to appliance housings, it ensures consistent results with fewer rejections and less post-processing. For high-tolerance applications, this masterbatch provides both functional integrity and production efficiency.

Frequently Asked Questions
Our FAQ section provides clear answers to common questions about white masterbatches, from product features to application details. We aim to help you understand how our solutions can improve your plastic products. If you have further inquiries, our team is always ready to assist you.
What causes shrinkage in plastic parts?
Thermal contraction during cooling and solidification of molten polymer.
How does this masterbatch reduce shrinkage?
By adding fillers and modifiers that resist volume loss and stabilize form.
What is the typical dosage level?
Between 5% and 25%, depending on part thickness and shrinkage requirement.
Is it compatible with injection molding and extrusion?
Yes—suitable for both processes.
Does it affect surface finish?
Slightly—it can reduce gloss depending on filler content. Glossy options are available.
Can it be used in food-contact applications?
Food-grade versions are available upon request.
Does it affect impact resistance?
Typically improves stiffness; impact resistance depends on filler type and dosage.
Can I use it with color masterbatch?
Yes, but slight color adjustment may be required to compensate for fillers.
Does it affect recyclability?
No—it remains compatible with most recycling systems.
Will it help with warpage in thin-wall parts?
Yes—it provides better dimensional stability even in thin-walled designs.
Is it suitable for high-precision parts?
Absolutely—it’s ideal for components requiring tight tolerances.
What types of fillers are used?
Talc, CaCO₃, glass beads, silica, mica, or nano clay depending on performance needs.
Can I use it in thermoforming?
Yes—it helps retain form in formed sheets or trays.
Does it impact the cycle time?
In most cases, it slightly improves cooling time due to better heat transfer.
Is it a permanent solution?
Yes—the effect lasts as long as the part exists.
Does it replace regrind loss?
It minimizes shrinkage even when regrind or recycled materials are used.
Can it be customized?
Yes—based on shrinkage %, resin type, and final application.
Is it better than post-processing warpage correction?
Definitely—prevention is more efficient and cost-effective than correction.
Does it help with flatness in sheets or panels?
Yes—it maintains geometry and reduces warping during or after extrusion.
