White crystal powder without any visible foreign matters. Soluble in water, slightly soluted in alcohol, dissolvable in benzene, ether and petroleum ether etc., Esters will be formed by reaction with common organic acid; No reaction take place when it is heated with dilute caustic solution. application Pentaerythritol is used in the manufacture of Alkyd resins, fatty acid rosin and tall oil esters and to make paint and coatings, printing ink, coating adhesives, explosives, sealants, varnish, lacquer, vinyl chloride, synthetic rubber and miscellaneous including Pentaerythritol tetranitrate (PETN), urethane coatings, flame retardant paints, polyvinyl chloride stabilizers, olefins antioxidant and Pentaerythritol triacrylate.
Catalyst for rosin ester,, shorten esterification process of different rosin esters, improve heat stability.We produce different kinds of esterification catalyst for gum and tall oil rosin esters. these catalyst can make esterification process quicker and improve the long term heat stability and reduce the color of these rosin ester at the same time.please send inquiry to us for detailed information and choose the suitable kind for your demand.Product Name: catalyst for rosin esterChemical Composition: phenol sulfide compounds or organophosphorous compunds� Synonym:Esterification catalyst� Antixidant for rosin ester� Stabilizer for rosin esterApplication:� 1.Catalyst for glycerine rosin ester2.Catalyst for pentaerythritol rosin ester3.Catalyst for modified rosin ester etc4.Catalyst for disproportionated rosinFeatures:â??Multifuncional:act as catalyst antioxidant and bleaching agent at the same timeâ??Better heat and light stability� â??Ordorlessâ??Environment friendlyâ??Approved for food contact applicationPackage:25kgs/kraft bag;25kgs/paper drum;25kgs/carton box or as customer's request;Storage:� Store catalyst for rosin ester in dry,cool and shady place.Keep the package sealed during not using it.Transportation:Our catalyst for rosin ester is not dangerous goods according to transport regulation.Shelf Life:2 years at least if stored as indicated aboveLead Time:Prompt delivery
Bleaching agent for rosin ester, catalyst for rosin ester, antixidant and stabilizer for rosin ester, make rosin ester with lighter color and better heat stability.We produce different kinds of bleaching agent for rosin ester.they are suitable for gum rosin ester and tall oil rosin ester including glycerine rosin ester, pentaerythritol rosin ester and some modified rosin ester etc.our bleaching agent can make these rosin esters and derivates with light color less than 3 gardner and act as catalyst and antioxidant, stabilizer at the same time. it means they make rosin ester with better heat resistance and long term color, storage stability. please send inquiry to us for detailed information andchoosing the best suitable kind for you demand.Product Name: Bleaching agent for rosin esterChemical Composition: phenol sulfide compoundsSynonym:Bleaching agent for rosin esterCatalyst for rosin esterAntixidant for rosin ester Stabilizer for rosin esterApplication:1.bleaching agent for glycerine rosin ester2.bleaching agent for pentaerythritol rosin ester3.bleaching agent for modified rosin ester etc4.bleaching agent for disproportionated rosinFeatures: Multifuncional:act as bleaching agent,antioxidant,light stabilizer and catalyst at the same time Make rosin ester with color less than 3 gardner at low dosage Better heat and light stability Ordorless Environment friendly Approved for food contact applicationPackage:25kgs/kraft bag;25kgs/paper drum;25kgs/carton box or as customer's request;Storage: Store bleaching agent for rosin ester in dry,cool and shady place.Keep the package sealed during not using it.Transportation:Our bleaching agent for rosin ester is not dangerous goods according to transport regulation.Shelf Life
