APSM is an effective and quickly dissolvable phosphorus-free auxiliary agent , and is considered the ideal substitution for STTP(Sodium triphosphate) .APSM is widely used in washing-powder,detergent,printing and dyeing auxiliary agent and textile auxiliary agent industries.
Product Features:
1. APSM is equal to STTP in terms of calcium and magnesium complexing performance.
2. APSM is highly compatible with any kinds of surface active agents (especially for non-ionic surface active agent), and stain removal capability is also satisfactory.
3. APSM easily dissolves in water, 15g minimum can be dissolved in 10ml of water.
4. APSM is capable of soakage, emulsification, suspending and anti-deposition; PH damping value is also desirable.
5. APSM is high in effective content, the powder is in high whiteness, and it's suitable to be used in detergents.
6. APSM with high performance price ratio is environment-friendly, it can improve the liquidity of pulp, increase solid content of pulp, and save energy consumption thus greatly reduces the cost of detergents.
7. APSM can be used as an auxiliary agent to partly replace or completely replace STTP, and meet the demands of users.
