Additivo+ Masterbatches: The Ultimate Guide to UV Protection, Mold Release & White MB

Guide Highlights

  • UV Masterbatch: Extends outdoor product life by preventing degradation.
  • PET Mold Release: Reduces cycle times and prevents sticking in bottle production.
  • White Masterbatch: High opacity TiO₂ solutions vs. cost-effective filler options.

In the competitive plastics industry, the difference between a good product and a great one often lies in the additives. Whether you need long-term outdoor durability, faster production cycles, or brilliant whiteness, Taprath’s Additivo+ range offers the solution.

“Enhance durability. Improve product quality. Protect your brand.”

1. UV Additive Masterbatch: Long-Term Durability

In today’s fast-growing plastic processing industry, long-term durability is a key requirement for outdoor and high-exposure applications. Constant exposure to sunlight can degrade polymers, causing discoloration, surface cracks, loss of mechanical strength, and reduced product life.

To overcome these challenges, our UV Additive Masterbatch offers a highly effective and economical solution for long-term UV protection.

How It Works

Our UV Additive Masterbatch combines two powerful protection mechanisms:

  • UV Absorbers: Absorb harmful UV rays and prevent degradation of polymer chains.
  • HALS (Hindered Amine Light Stabilizers): Neutralize free radicals formed during UV exposure.

Together, they offer comprehensive protection that significantly enhances product lifespan.

Impact of UV Additives on Mechanical Strength

Comparison: Without UV (Grey) strength drops rapidly. With Additivo+ (Blue) strength is retained.

Applications

Our UV-stabilized masterbatch is ideal for:

Agricultural films
Outdoor furniture
Water tanks
Woven sacks & raffia

2. PET Mold Release Additives: Improve Your Process

Processing PET can be smooth… or a total headache, depending on how your mold behaves. One of the biggest challenges manufacturers face is parts sticking to the mold, causing downtime, defects, and higher production costs.

That’s where PET Mold Release Additives step in—they’re basically the silent heroes that keep your production line running clean and fast.

How Release Additives Actually Work

Most PET mold release additives are fatty acid derivatives or functionalized waxes. When the PET melts, the additive migrates to the surface and creates a thin lubricating layer between the part and the mold.

Without Additives
  • Longer cycle time
  • Increased scrap rate
  • Mold damage risks
With Additivo+
  • Faster release
  • Lower ejection force
  • Extended mold life
Production Efficiency: Cycle Time Reduction

Using Additivo+ reduces cycle time significantly compared to standard PET.

Whether you’re producing bottles, preforms, or technical parts, the right additive can completely change your processing experience.

3. White Masterbatch: TiO₂ vs. Non-TiO₂

White Masterbatch is one of the most widely used color concentrates in plastics processing. Depending on application needs, processors use two types:

  1. White Masterbatch With TiO₂ (Titanium Dioxide)
  2. White Masterbatch Without TiO₂ (Filler / Polymer-based White)

Comparison Table

Property With TiO₂ (Premium) Without TiO₂ (Economy)
Opacity Highest (Excellent Hiding) Low – Medium
Whiteness Very High / Bright Moderate (Natural)
UV Protection Strong Minimal
Cost Higher Very Low
Best For Injection molding, High-end films Carry bags, Laminations

Which One Should You Choose?

  • Choose TiO₂ White MB when you need: High whiteness, high opacity, UV protection, and a premium product finish.
  • Choose Non-TiO₂ White MB when you need: Low-cost whitening, added stiffness, non-critical opacity, and cost reduction.

Frequently Asked Questions

What is UV Additive Masterbatch? +
It is a formulation of UV stabilizers and absorbers added to plastics to protect them from degradation caused by sunlight.
How do PET mold release additives work? +
When the PET melts, the additive migrates to the surface and creates a thin lubricating layer between the part and the mold, allowing for faster release.
What is the difference between TiO₂ and Non-TiO₂ White MB? +
TiO₂ based masterbatches provide superior whiteness and opacity for premium products. Non-TiO₂ (filler-based) are cost-effective solutions for applications where high opacity is not critical.
