Trimethylolpropane (CAS Nr .: 77-99-6)Product Overview
Product Description
Trimethylolpropane (TMP, 2-Ethyl-2-(hydroxymethyl)-1,3-propanediol, CAS 77–99–6) yog non-toxic, trifunctional thawj polyol nrog peb pawg hydroxyl reactive. Nws zoo nkaus li dawb crystalline khoom nyob rau hauv chav tsev kub (lub ntsiab lus melting ntawm ≈ 58-61 degree) thiab yog dav siv los ua ib lub tsev thaiv nyob rau hauv lub synthesis ntawm alkyd resins, polyurethane (PU) dispersions, high-khoom coatings, hluavtaws lubricants (trimethylolpropane esters), thiab hluav taws xob-kho monomers. Nws cov qauv trifunctional muab zoo heev crosslinking ceev, ua rau cov khoom kawg nrog superior hardness, tshuaj tsis kam, thiab weatherability.

Qhov zoo - Vim li cas thiaj xaiv peb TMP
Kev ua haujlwm siab dua li (diols):
Peb pawg OH thawj zaug muab kev ua haujlwm zoo thiab kev sib txuas ntawm kev thauj khoom qis.
Cov huab cua zoo dua li pentaerythritol hauv alkyds:
TMP-raws li alkyd resins qhia txhim kho gloss retention thiab saj zawg zog yam tsis muaj kev cuam tshuam hardness.
Tsawg volatility thiab zoo thermal stability:
Haum rau siab -kub kho tshuab (piv txwv li, coil txheej, hmoov txheej).
Kev cai lub cev daim ntawv:
Muaj raws li flake lossis hmoov kom yooj yim tuav thiab hnyav.
Cov txiaj ntsig - Cov neeg siv khoom tau txais dab tsi
Rau txheej manufacturers (kev lag luam, tsheb, ntoo):
TMP txhim kho hardness, stain resistance, thiab sab nraum zoov durability ntawm polyester thiab PU coatings → ntev khoom lub neej thiab txo repainting zaus.
01
Rau alkyd resin producers
TMP muab cov khoom hnyav molecular hnyav nrog qis viscosity, tso cai rau siab - cov khoom tsim ua raws li VOC cov cai → yooj yim dua daim ntawv thov thiab kev tswj xyuas.
02
Rau hluavtaws roj formulators (ISO VG 46, 68 thiab lwm yam.):
TMP esters muab siab viscosity Performance index (VI> 140) thiab qis qis taw tes → zoo zog efficiency thiab txuas ntxiv roj ntws.
03
Rau UV- kho tau monomer makers:
TMP triacrylate (TMPTA) muab cov lus teb kho sai thiab ua kom zoo rau cov yas / hlau → siab dua thiab muaj zog ntawm daim ntawv cog lus.
04
Pov thawj
- COA (Certificate of Analysis)muab nrog rau txhua pawg, suav nrog GC chromatogram thiab hydroxyl tus nqi kuaj daim ntawv qhia.
- 24-hli kev kawm ruaj ntsegnyob rau hauv qhuav, txias cia (qis dua 35 degree) qhia purity poob <0.2% thiab tsis muaj acid nqi tseem ceeb drift.
- Cov neeg siv khoom:Ib tug Turkish txheej tsim tau hloov pentaerythritol nrog peb TMP nyob rau hauv lawv coil txheej formulation thiab txhim kho rov qab cuam tshuam los ntawm 40 mus rau 60 nyob rau hauv -lb yam tsis poob mem hluav hardness (2H).
- Logistics pov thawj:Peb xa tawm qhov nruab nrab ntawm 500 tons ntawm TMP txhua hli rau cov neeg siv khoom hauv Europe, Southeast Asia, thiab Middle East, nrog <0.3% zoo- cuam tshuam txog kev tsis txaus siab tshaj 24 lub hlis.
