HM-800 is a bio-based polyester plasticizer developed for flexible PVC formulation work. According to the supplied product information, it is synthesized from vegetable-oil acid, dibasic acid and fatty alcohol through esterification, polymerization, epoxidation and related reactions. For compounders and converters, it provides a defined starting point for evaluating plasticizer selection in flexible-PVC systems while maintaining traceability from incoming material through finished-article assessment.
The published product specification identifies HM-800 as a light-yellow transparent liquid at 25°C or above. The stated control values include colour of no more than 150 Pt-Co, acid value of no more than 0.3 mg KOH/g, iodine value of no more than 3.0%, epoxy value of at least 3.5%, flash point of at least 230°C, moisture content of no more than 0.2%, and viscosity of 150–300 cps at 25°C. These values can help procurement, technical service and production teams align incoming-material checks with the approved product documentation.
In flexible-PVC development, a plasticizer is evaluated as part of a complete formulation rather than in isolation. Resin type, filler level, stabilizer package, pigments, processing method and target article all influence the result. HM-800 should therefore be assessed using the actual compound and production route under consideration. A structured evaluation may compare a defined HM-800 formulation with an existing internal reference, while keeping the PVC resin, additive package, processing conditions and test methods clearly documented.
Illustrative formulation scenario: A development team prepares a small flexible-PVC compound series using one approved PVC resin and a fixed stabilizer package. It introduces HM-800 at predetermined formulation levels, processes each blend using the same laboratory route, and records mixing behavior, sheet appearance and selected internal test observations. The team then decides whether further formulation adjustment is justified. This is an illustrative development scenario, not a customer case or performance guarantee.
The supplied product information lists potential application areas including flexible PVC products, cable-related materials, artificial leather, shoe materials, waterproofing membranes and sealing strips. Such references should be treated as application-development directions. Final suitability depends on the specific formulation, conversion process, service conditions and customer specification. Claims relating to food contact, children’s products, migration, regulatory compliance, extraction resistance, weathering, safety or environmental performance must be supported by product-specific and finished-article-specific evidence before external use.
HM-800 is supplied in packaging options stated as 200 kg iron drums and 1,000 kg flexitanks. The product information also notes that the material may solidify between 5°C and 10°C and may be restored to a transparent state by warming above 25°C. Storage, heating, handling and quality-release procedures should be confirmed against the current controlled technical data sheet and safety documentation.
What is HM-800? HM-800 is a bio-based polyester plasticizer for flexible-PVC formulation development, with the technical values stated in the controlled product documentation.
Can HM-800 be advertised as food-contact compliant? Not without product-specific regulatory review, migration testing and finished-article validation for the intended jurisdiction and use conditions.
Can the published specification replace an incoming inspection plan? No. The approved specification, current certificate of analysis and the purchaser’s own quality requirements should all be used for release decisions.
