Amorphous copolymer polycar bonate SP-2230

Polycarbonate (PC), as a material with superior comprehensive performance, has a wide range of applications including electronic devices, medical equipment, automotive parts, etc. However, it does not have the ability to resist the erosion of various chemical agents, which to some extent limits its application scope. In the post pandemic era, people's living habits have undergone earth shattering changes, and disinfectants have become important partners in daily life. Faced with the increasingly severe problem of chemical erosion, we have found a new solution - chemical resistant copolymer PC SP-2330&SP-1830. This material is modified by blending with general-purpose PC, ABS or PBT to form an alloy plastic, which has the properties of chemical resistance, low temperature impact resistance, lightweight thin-walled flame retardancy.
Purpose: SP-2330 is only used as a raw material for modified mixing and is not suitable for direct injection molding or compression molding applications.

PC material modified by SP-2330 blending and domestic 92 # gasoline tolerance test
Gasoline is a volatile, combustible mixture of hydrocarbons, a common chemical and solvent, fractionated and cracked from petroleum. Many amorphous thermoplastics break or degrade after contact with gasoline. The non-transparent grade SP-2330 and transparent grade SP-1830 of chemical-resistant polycarbonate developed by Yuan Chong Chemical underwent a series of gasoline contact resistance tests. The modified material mixed with SP-2330 and SP-1830 has a certain tolerance to gasoline contact. In addition to gasoline, SP-2330 and SP-1830 have good cracking resistance against a wider range of medical disinfectants, household disinfectants and chemicals. Please refer to the table below for details.
