Isophthalic Acid Supplier in Malaysia
- Also known as
- Benzene-1,3-Dicarboxylic Acid
- Meta-Phthalic Acid
Isophthalic acid is supplied as an aromatic dicarboxylic-acid intermediate for resin, coating and polymer manufacturers in Malaysia. Also called benzene-1,3-dicarboxylic acid, it is a white crystalline powder selected for polyester, alkyd and specialty-resin synthesis.
Commercial requirements commonly cover purified and resin-grade material with defined purity, colour, moisture and impurity limits. Isophthalic acid is a separate positional isomer from terephthalic acid, so buyers should identify the required diacid rather than treating the names as interchangeable.
Applications include unsaturated polyester resins, corrosion-resistant composite systems, polyester and alkyd coatings, copolymers and engineered polymer intermediates. Grade selection is tied to the reaction route, final resin colour and performance specification.
Send the required grade, purity, colour or impurity limits, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed for the quoted isophthalic acid grade.

Common questions about isophthalic acid
What is isophthalic acid used for in resin production?
It is used as an aromatic diacid in unsaturated polyester, alkyd, coating and copolymer systems where the resin designer requires its meta-linked structure and performance contribution.
Is isophthalic acid the same as terephthalic acid?
No. They are separate positional isomers and are selected for different polymer and resin designs. Specify isophthalic acid by name when the formulation requires it.
Which grade should be requested for polyester resin?
Provide the target resin chemistry, purity, colour and impurity limits, plus any current specification used for production approval. The quotation can then address the correct grade.
Can isophthalic acid be used in corrosion-resistant composites?
Isophthalic unsaturated polyester resins are used in selected composite systems, but the final performance depends on the complete resin formulation, reinforcement, cure and service conditions.
What details are needed for an isophthalic acid quote?
Include grade, purity, colour, impurity limits, end use, quantity, delivery location and required documents or sample approval steps.
