Executive Summary

A single compound that does the work of four.

Rubber manufacturers carry unnecessary complexity in their compound rooms — multiple chemicals to store, scorch loss that's written off, shelf-aged material that's discarded. FLEXIAID collapses that complexity into one addition.

The Problem

Complexity, loss, and stranded inventory.

Multiple chemicals to store — plasticizers, retarders, dry-flow, process aids
Scorched rubber: compound cost, inventory carry, disposal fees
Shelf-aged compounds with failing properties and poor flow
Rejected parts with no recovery path

The Solution

FLEXIAID — proprietary zinc-based multi-function chemistry.

One compound, four simultaneous functions in processing
Restores and extends the shelf life of rubber compounds
Replaces peptizers, plasticizers, retarders and processing aids
Works across every rubber type and production method

The Result

Lower cost, higher yield, cleaner supply chain.

Lower raw material and disposal costs per batch
Less scrap — improved yield per production run
TGA analysis confirms undetectable devulcanization loading with enhanced post-ageing compound properties
TSCA and REACH compliant across the supply chain

Multi-functional

Why one molecule does four jobs.

FLEXIAID is a proprietary zinc-based complex compound engineered specifically for the rubber industry. Unlike single-function additives, it acts simultaneously across every stage of compound life.

"Not a blend. Not a dosage reduction. A genuine functional replacement for four separate chemistries."

01 — Process Aid

Improves flow and processability.

Increases plasticity, fluidity and lubrication of the rubber compound during mixing and extrusion. Higher throughput, smoother surfaces, cleaner extrusion profiles.

02 — De-Crystalizer

Reverses storage-induced crystallization.

Breaks down crystalline structures that form in stored or aged rubber — restoring workability and flexibility to compounds written off as unusable.

03 — De-Scorcher

Prevents and reverses premature cure.

Prevents and reverses premature vulcanization during processing. Recovers scorched compounds typically routed directly to scrap — back to usable inventory.

04 — De-Vulcanizer

Enhanced Processability of Off-Grade Polymers & Reclaims

Enabling devulcanization, reprocessing and reuse of rejected parts, flashes and cured scrap.

What It Replaces

Four separate chemicals, now one line item.

FLEXIAID doesn't reduce dosage of each chemical. It functionally replaces each one — simplifying your BOM, reducing SKU count in the compound room, and cutting procurement complexity.

Peptizer

Oxidation catalysts or radical acceptors used to break down rubber molecular chains for easier processing. FLEXIAID achieves equivalent molecular breakdown without a dedicated peptizer.

→

Plasticizer

Synthetic resins used to promote plasticity, flexibility and reduce brittleness in compounds. FLEXIAID improves flow and pliability without any separate plasticizer addition.

→

Retarder

Used to prevent premature vulcanization during mixing and processing. FLEXIAID's de-scorching function provides built-in scorch protection across the entire process window.

→

Processing Aid

Chemical additives used to increase plasticity, fluidity or lubrication of a compound. FLEXIAID simultaneously functions as a process aid — improving flow throughput and surface quality.

→

Compatibility

Process Integration

From fresh compounding to reclaim recovery.

FLEXIAID integrates at every stage of rubber production — whether you're mixing a new batch or recovering scorched stock. Same product, same mill, different role.

01 — Forward Process

Vulcanization

Used during standard sulfur vulcanization to improve compound flow, prevent premature cure and enhance the final cross-linked properties of the rubber product.

Applications

Fresh compound mixing
Injection moulding
Extrusion & calendering
Compression moulding

02 — Reverse Process

De-Vulcanization

Breaks down existing cross-links in vulcanized rubber — enabling scrap recovery, reclaim processing and reintroduction of off-grade material into the production cycle.

Applications

Scorched compound recovery
Off-grade rubber reprocessing
Reclaim rubber grain orientation & activation
Flash & reject recovery

Recovery Workflow

Cold de-vulcanization in four steps.

No thermal input. No specialized equipment. Just your existing open mill or internal mixer — and FLEXIAID.

Step 01

Identify scrap material

Scorched stock, off-grade parts, rubber flashes and quality-rejected compounds are identified for recovery.

Step 02

Add FLEXIAID at 3–5 PHR

Introduce FLEXIAID at recommended dose into the open mill or internal mixer along with the material to be recovered.

Step 03

Cold mix process

Process at ambient temperature — no external heat source required. Cross-links break down progressively under mechanical shear.

Step 04

Recovered compound

Material regains plasticity, processability and physical properties — ready to re-enter the production cycle.

FLEXIAID alone — one addition, all functions

Dosage Guide

Simple PHR dosing. No reformulation.

FLEXIAID integrates directly into your existing compound recipe — added to the open mill or internal mixer alongside the rubber and other ingredients.

PHR = Parts per Hundred Rubber. Add FLEXIAID directly to the mixer or open mill with the rubber compound. No specialized equipment or feed systems required.

2^PHR

Fresh Compound

New batch production

Add 2 parts FLEXIAID per 100 parts rubber for new compound production. Improves processing, prevents scorching, and enhances final aging properties.

Standard production

3–5^PHR

Scorched / Aged / Off-Grade

Recovery & reclaim

Higher dosage required to fully de-vulcanize and restore heavily deteriorated or scorched compounds. Start at 3 PHR and increase based on material condition.

Recovery / reclaim

Measurable Advantages

What FLEXIAID delivers on the floor.

Measurable advantages at every stage of rubber production — from raw material cost to finished product aging.

Reduces chemical dependency

Replaces or reduces plasticizers, retarders, dry-flow chemicals and general process aids — simplifying your ingredient stack.

Cost savings via scrap recovery
