Chinese Polyurethane Raw Material Alternatives

Replace Wanhua, BASF, Dow at Lower Cost — High-Quality Equivalents with Same CAS Numbers

Wanhua PM200 Alternative

PM200 is already a top-tier polymeric MDI widely used in rigid foam insulation applications. DOBO Chemical supplies polymeric MDI (CAS 9016-87-9) directly at competitive pricing, offering the same performance characteristics as Wanhua PM200 without the premium brand markup.

CAS Number: 9016-87-9 | Application: Rigid foam insulation, spray foam, panel production

BASF Lupranate Alternative

For buyers seeking alternatives to BASF Lupranate polymeric MDI series, DOBO Chemical offers Wannate 8310 and MDI-50 as direct equivalents. These products deliver comparable reactivity profiles and foam stability at significantly lower costs.

CAS Number: 9016-87-9 | Equivalent Products: Wannate 8310, MDI-50

Dow Voranol Alternative

Dow Voranol polyether polyols are industry benchmarks for flexible foam production. DOBO Chemical's DEP-5631D and DEP-3500D polyether polyols (CAS 9003-11-6) serve as reliable Chinese alternatives with consistent hydroxyl values and viscosity profiles.

CAS Number: 9003-11-6 | Equivalent Products: DEP-5631D, DEP-3500D

Huntsman Suprasec Alternative

Huntsman Suprasec polymeric MDI is commonly used in spray foam and panel applications. DOBO Chemical's PM200 polymeric MDI provides a direct replacement with identical NCO content and functionality, ensuring seamless formulation transitions.

CAS Number: 9016-87-9 | Application: Spray foam, rigid panels

Covestro Desmodur TDI Alternative

Covestro Desmodur TDI is a standard choice for flexible foam manufacturing. DOBO Chemical supplies TDI 80/20 (CAS 584-84-9) with the same 80:20 isomer ratio, delivering equivalent reactivity and foam properties for mattress, furniture, and automotive applications.

CAS Number: 584-84-9 | Isomer Ratio: 80/20

Evonik Dabco / Momentive Niax Alternative

For amine catalysts and silicone surfactants, DOBO Chemical offers A33 amine catalyst (CAS 280-57-9) and L-580 silicone surfactant as cost-effective alternatives to Evonik Dabco and Momentive Niax products, maintaining consistent catalytic activity and foam stabilization.

CAS Number: 280-57-9 (A33) | Products: A33 Amine Catalyst, L-580 Silicone Surfactant
