TDI & Industrial Materials
From grade specifications to supply arrangements, make purchasing requirements clear.
Chemical Supply Starts with Specifications
As a supply partner, we coordinate product specifications, technical documents and order arrangements for TDI and related chemical materials.
TDI 80, TDI 65 and TDI 100 are reviewed separately against their grade and application requirements. PVC, urea and other products are discussed according to the destination, specification and available supply.
Core Products
TDI is our focus; other products are reviewed by grade and availability.
Product illustrations; packaging and grade are confirmed for each order.

PVC or CPVC? Start with the application
| Selection point | PVC | CPVC |
|---|---|---|
| Application focus | Pipes, profiles, cable materials and films | Pipes, fittings and industrial materials requiring heat resistance |
| Define first | Process, grade / K-value and formulation requirements | Resin or compound; temperature, pressure and contact medium |
| Documents to review | Grade-specific TDS, current SDS and the required batch COA. Use the selected grade’s documents for performance and application limits. | |
TDI
Enquire about TDI 80, TDI 65 and TDI 100. Provide the grade, application, quantity and destination so specifications, packaging and availability can be reviewed.

In-depth Understanding of Our Core Products' Mechanisms and Practical Application Scenarios
DAP Functions
Application and grade
Specify agricultural or industrial use for diammonium phosphate, then establish the corresponding specification.
Quality parameters
Share target assay, moisture and impurity requirements and request the specification and batch COA.
Sourcing conditions
Review particle size, packaging, quantity and destination without assuming a crop-yield outcome.
Urea Functions
Grade selection
Select urea for agricultural, industrial or another specified use, using formal documents for the chosen grade.
Parameter review
Confirm assay, biuret, moisture and impurity limits; appearance alone does not determine grade.
Delivery and storage
Arrange sourcing against packaging, destination and storage requirements, with batch documents checked before supply.
TDI Functions and Applications
Polyurethane Manufacturing
TDI is the core raw material for producing polyurethane foam, elastomers, coatings, and adhesives.
Industrial Applications
Widely used in polyurethane product manufacturing in automotive, construction, furniture, and footwear industries.
PVC Role and Application
Pipes and profiles
Select the grade for the process, mechanical requirements and service conditions.
Wire and cable
Confirm the formulation and grade for the required electrical, processing and flame-performance properties.
Film and packaging
Review clarity, flexibility and intended contact use. Food or pharmaceutical contact applications require appropriate supporting documentation.
CPVC selection and applications
Hot-water pipes and fittings
Confirm service temperature, pressure, processing method and destination requirements before selecting a grade.
Industrial piping and materials
Review compatibility for the contact medium, concentration and temperature.
Resin and compound
Specify the required material form and review grade-specific documents. Application illustrations do not represent finished-product certification.
Responsible Supply Cooperation
