 AMS |
 |
|
 GENERAL |
 |
Alpha-methylstyrene,
which is also referred to as isopropenyl benzene,
is an organic chemical used to produce a wide
variety of styrenic polymers. AMS adds heat
resistance to ABS resins which can be found
in automotive parts, electronic appliance
housings and protective coatings. AMS is used
in the production of para-cumylphenol, a specialty
intermediate for thermoplastics and polycarbonate
resins. Health and safety information is available
through the appropriate Material Safety Data
Sheet(MSDS). |
