Products Application
Polymer material modification
Heat-resistant modifier: can significantly improve the heat resistance temperature of styrene-based resins such as ABS, PS, and ASA, enabling them to be used in higher-temperature applications.
Alloy compatibilizers: can effectively improve the interfacial bonding when incompatible polymers are blended.
Dispersion/coupling of glass fiber, mineral powder, pigment, and carbon materials.
Coatings, inks, adhesives and paper treatment
High-performance coatings: Used as film formers in industrial coatings. In the fields of automobiles and electronics, it is also used to prepare self-healing coatings or electroplating enhancement layers.
Adhesives and coupling agents: can be used to improve the bonding strength between resins and substrates such as metals and fiberglass.
SMA foam materials: building insulation boards, sound insulation materials, and packaging cushioning materials.
As a tanning or finishing agent, it improves the feel and filling properties of leather.
In the electronics field, it can be used to prepare insulating and packaging materials.
FAQ
Q: Is there a discount?
A: Yes, different quantity with different quotations.
Q: Were all goods inspected before delivery?
A: Yes, before the goods are sent out, we'll conduct a 100% full inspection on all goods.
Q: What's your after-sales service?
A: We will inform you of the progress of the order, such as product preparation, declaration, transportation follow-up, customs clearance assistance, etc.
Q: How to start an order or make payment?
A: A PI document will be sent first after confirmation of the order, enclosed with our bank information. Payment by T/T, Western Union, LC, Alibaba Trade Assurance, MoneyGram, or PayPal.
Q: Why can SMA be used as a compatibilizer?
A: The styrene segments provide a nonpolar aromatic structure, giving SMA good compatibility with styrene-based systems such as PS, SAN, ABS, ASA, and PMMA/ABS. The maleic anhydride segments provide anhydride groups, enabling SMA to react with or form strong interactions with materials containing active groups such as hydroxyl, amino, epoxy, and amide groups.
