Micronized Pentaerythritol for Textile Coatings
Halogen-free char-forming performance to achieve strict FR standards (BS 5852 / NFPA 701) without compromising softness, drape, or color.
Ultra-Soft
Hand Feel
Zero
Chalking
Invisible Protection. Uncompromised Softness.
Common challenges with FR coatings - and how micronized pentaerythritol solves them.
The Problem with Traditional Systems
Stiff Hand Feel
Coating feel rigid and boardy, affecting drape and comfort.
Chalking & White Spots
Surface bloom and white residues ruin color and appearance.
Applicator Clogging
Larger particles lead to poor dispersion and line downtime.
Micronized Pentaerythritol Solution
Ultra-Soft Hand Feel
Micronized particles enable smooth, flexible coatings with natural drape.
Zero Chalking
Excellent compatibility and low migration for clean, vibrant fabrics.
Smooth Application
Fine, uniform particles disperse easily, reducing filter blockage and defects.
Char-Forming & Anti-Dripping Mechanism
Synthetic fibers melt and drip when exposed to flame, accelerating fire spread. Our system forms a protective barrier that prevents dripping and blocks oxygen.
1. Heat Exposure
Synthetic fibers soften, melt and begin to drip when exposed to flame.
2. Foamed Char Formation
Pentaerythritol works with APP to form an intumescent char layer.
3. Barrier Effect
The foamed char insulates and blocks oxygen and heat transfer.
4. Stop Dripping. Stop Burning
The stable char prevents flaming drips and limits fire propagation.
Result:
Safer textiles with better aesthetics and performance.
Why It Matters
Complete Textile Coating Finishing Agent System
Customers never formulate with just flame retardants - they use complete systems. Micronized PER is designed for seamless integration with the entire finishing agent ecosystem.
1. Binders / Film Formers
(Acrylic, PU)
Role: Keeps flame retardants adhered to fabric creating a durable coating.
Why related to PER: Must have excellent compatibility; avoid stratification or precipitation that ruins storage stability.
Common Problem: Incompatibility leads to paste separation and poor shelf life.
How Micronized PER Solves It: Superior compatibility ensures stable, uniform formulations.
2. Crosslinkers
Role: Improves wash and abrasion durability of coating.
Why related to PER: Affects system pH and stability. PER must remain stable in this chemical environment.
Common Problem: pH shifts or instability cause performance loss over time.
How Micronized PER Solves It: Chemically stable across pH range; maintains performance and shelf stability.
3. Water / Oil Repellents
(Fluorine / Silicon Finishers)
Role: Impart water and oil repulsion to fabric.
Why related to PER: Easily react with other additives. PER must enable char formation without compromising these functions.
Common Problem: Repellency loss or reduced durability after laundering.
How Micronized PER Solves It: Ensures effective char with minimal impact on water/oil repellency.
4. Hand-Feel Modifiers
Role: Keep coating soft and non-stiff.
Why related to PER: Coarse particles make coatings harsh or rough; micronized PER significantly reduces this impact.
Common Problem: Stiff, rough hand feel and reduced comfort.
How Micronized PER Solves It: Fine particle size delivers smoother, softer fabrics.
5. Dispersants / Wetting Agents
Role: Ensure uniform distribution of flame retardants in paste.
Why related to PER: Micronized PER has superior inherent dispersibility; reduces dispersant dependency.
Common Problem: Poor dispersion causes settling, caking and uneven performance.
How Micronized PER Solves It: Excellent dispersibility simplifies formulation and improves stability.
6. Other Functional Additives
(Anti-static, Antimicrobials, Brighteners)
Role: Add specialty functions to coating.
Why related to PER: Entire chemical environment affects PER char efficiency and FR performance.
Common Problem: Additive interactions reduce FR effectiveness.
How Micronized PER Solves It: Compatible with diverse additives; maintains high FR performance.
