About Polycarbonate Polymer

Organic polymers have been part of detergents and cleaners formulation for many years. Polymeric builders in the form of anionic polycarboxylates based on acrylic acid account for more than 90% of all polymers used in detergents. The main function of polymers is of acting as anti soil redeposition agent. Apart from this, polymers help in part replacement of builders like STPP and also inhibit unwanted hydrolysis which results in loss of active substance. It is used for application in detergent, cleaners as well as personal care industry.

Useage

Inhibition of crystal growth, thus preventing precipitation of carbonates phosphates or silicates on fabric.
Dispersion of precipitates in the cleaning bath to avoid setting and scaling on surfaces and fibres.
Prevents the redeposition of clay sink onto the fabric or hard surface by keeping the particles suspended in the wash bath.
Effective Inorganic Cleaning agent / dirt repellent.
Very good sequestration ability. Removes Calcium Ion keeping it in a dissolved state.
Improvement of filming maintenance by soil dispersion, which minimize organic components deposition on glass and dishwares.

These additives help protect the material from yellowing and degradation due to prolonged exposure to sunlight.

Q: What are the recommended processing methods for this grade of polycarbonate?

A: This polycarbonate polymer is designed for use with injection molding, extrusion, and blow molding techniques. These processing methods allow precise shaping and efficient mass production, making the material suitable for complex components in various industrial applications.

Q: Where is high-impact polycarbonate most commonly utilized?

A: Due to its high impact strength and excellent transparency, polycarbonate finds frequent use in automotive components, electronics housings, medical devices, eyewear lenses, construction glazing, and optical media such as CDs and DVDs.

Q: What benefits does polycarbonate offer compared to other engineering plastics?

A: Polycarbonate stands out for its unique combination of high mechanical strength, self-extinguishing flammability, optical clarity, and excellent electrical insulation. These properties, along with its non-toxic and odorless profile, make it advantageous for applications requiring safety, performance, and aesthetics.

Q: How should polycarbonate granules be stored to maintain quality?

A: To preserve quality and prevent moisture absorption, polycarbonate granules or pellets should be stored in a cool, dry, and well-ventilated area, away from direct sunlight. Proper storage helps maintain material properties and processing performance.

Q: What is the water absorption rate and how does it affect polycarbonate usage?

A: Polycarbonate exhibits a low water absorption rate of 0.15% after 24 hours at 23C. This low absorption helps maintain dimensional stability and mechanical properties, even in humid environments or applications involving light exposure to moisture.
