99.8% Adipic Acid CAS 124-04-9 Crystal Granule Organic Chemical Raw Material for Nylon 66 Polyurethane & Food Acidity Regulator Factory Supply

Product Description

Brief Overview

Adipic acid, chemical name Hexanedioic Acid, is a saturated aliphatic dicarboxylic acid with linear carbon chain structure, produced through cyclohexane oxidation process. It appears as uniform white crystal granule, free from lumps, impurities and discoloration. Our factory supplies two complete grades: Industrial Grade and Food Grade, both with guaranteed minimum purity of 99.8%. As a fundamental organic chemical intermediate, it occupies an irreplaceable position in nylon synthesis, polyurethane manufacturing, plasticizer industry and food additive field. We have stable monthly production capacity, full export certification system, flexible packaging solutions and one-stop foreign trade logistics service for global buyers.

Wide Range of Applications
1. Industrial Grade Adipic Acid (Main Stream Demand)
Nylon 66 Core Raw Material
The largest consumption field: polycondensation with hexamethylenediamine to produce Nylon 66 salt, then make nylon fiber, tire cord fabric, engineering plastic, injection molding resin and extruded nylon parts for auto, machinery and textile industries.
Polyurethane Series Products
Key raw material for polyurethane shoe sole stock, PU synthetic leather, PU elastomer, cast PU rubber, waterproof coating and adhesive, endows finished products good elasticity, wear resistance and low temperature resistance.
Plasticizer & Coating Additive
Used to synthesize dioctyl adipate (DOA), dibutyl adipate (DBA), environment-friendly cold-resistant plasticizer for PVC film, artificial leather, cable sheath, water-based resin and anticorrosive paint.
Organic Synthesis Intermediate
Applied in production of lubricant additive, pesticide intermediate, dyestuff, curing agent for epoxy resin, water treatment chemical and corrosion inhibitor.
2. Food Grade Adipic Acid (Food Additive Field)
Food Acidity Regulator & Sour Agent
Widely used in carbonated drinks, fruit juice, jelly, gummy candy, pectin jam, baked pastries, margarine, dairy dessert. It delivers mild, lasting sour taste without harsh bitter aftertaste, better taste performance than citric acid in gel food.
pH Buffering Stabilizer
Adjust and stabilize food pH value, extend shelf life, improve texture of gel food, prevent sugar crystallization in candy production.
Animal Feed Additive
Small dosage added into feed to balance gastrointestinal acid-base environment of livestock and poultry, promote nutrient absorption.

Purchase FAQ
Q: Can I mix industrial grade and food grade in one container?
A: Not recommended. We arrange separate production and independent loading to avoid cross-contamination, two grades will be shipped separately.
Q: Is adipic acid hazardous chemical?
A: No, it belongs to general organic chemical, non-flammable, non-explosive, low irritation to human skin.
Q: What is the minimum order quantity?
A: 1 ton for sample trial order; full 20GP container (20 tons) for mass bulk order.
Q: How to avoid caking during long sea transportation?
A: We use thickened PE inner liner ton bag, control product moisture strictly below 0.18%, add anti-caking agent on special customer request.
