Quick facts
- ISO FR TDS identity
- Halogen-free, ATH-filled isophthalic-based FR grade
- Standard FR TDS identity
- Separately published halogenated FR UPR grade
- Selection rule
- Begin with the project requirement and exact grade data
- Not established by the documents
- A universal fire or performance hierarchy
Compare the documented product identity first
Samrat FRP Traders publishes ISO Fire Retardant Resin and standard Fire Retardant Resin as separate products. The ISO FR TDS describes an isophthalic-based, halogen-free, ATH-filled fire-retardant grade. The standard FR TDS describes a separate halogenated fire-retardant UPR grade.
That distinction helps a buyer begin the discussion, but it does not prove that either grade is universally stronger, more durable, more fire resistant or suitable for every finished FRP system.
Do not compare names without the project requirement
Record whether the requirement specifically calls for isophthalic chemistry, a fire-related project specification, particular documentation or a defined finished component. Then review the current grade-specific TDS for the material route being considered.
If a project requires a particular test method, classification or tested configuration, share the original wording. A resin designation alone does not confirm a finished-part classification.
Use the comparison to improve the enquiry
Ask the supplier to review the intended FRP component, required documentation, project requirement, quantity, packaging and delivery location against the two published grades. If the requirement is ordinary general FRP rather than a specialised FR selection, review the separately published GP and UPR routes instead.
Frequently asked questions
Is ISO Fire Retardant Resin simply the same as standard Fire Retardant Resin?
No substitution should be assumed from the names. The current TDS documents identify separate product routes and different published chemistry descriptions. Review the exact grade data and the finished application before selection.
Which Fire Retardant Resin is better?
The available documents do not establish a universal better grade. The relevant choice depends on the required chemistry, finished application, documentation request and any project fire-performance requirement.
