PS Sheet is a widely used plastic material, which is favored for its excellent transparency, easy processing and low cost. However, in different application scenarios, the performance requirements of PS sheets vary significantly. The following is an analysis of the specific performance requirements of PS sheets in the fields of packaging, advertising display, building materials and electronic appliances:

Packaging field
Performance requirements: PS sheets for packaging need to have good transparency, impact resistance and easy molding, while meeting food grade or environmental protection standards.
Applicability optimization:
Transparency: High transparency helps to show the appearance of the product and enhance visual appeal.
Impact resistance: Improve the toughness of PS sheets to prevent damage during transportation or handling.
Food safety: Ensure that the material is non-toxic and harmless and meets food contact standards (such as FDA certification).
Degradability: Develop recyclable or biodegradable PS sheets to reduce environmental impact.
Advertising display field
Performance requirements: PS sheets for advertising display are mainly used to make light boxes, display boards and signboards, and need to have high transparency, color reproduction and durability.
Applicability optimization:
Optical properties: Improve the light transmittance and UV resistance of the board to ensure that it does not turn yellow or deform after long-term use.
Surface treatment: Anti-glare, waterproof or antibacterial functions are achieved through coating or printing technology.
Structural design: Increase thickness or adopt multi-layer composite structure to improve rigidity and load-bearing capacity.
Environmental protection: Use materials with low volatile organic compounds (VOC) to reduce the impact on indoor air quality.
Building materials field
Performance requirements: PS boards for architectural decoration are usually used for ceilings, partitions or exterior wall decoration, and need to have flame retardancy, weather resistance and good thermal insulation properties.

Applicability optimization:
Flame retardant performance: Add high-efficiency flame retardants or develop intrinsically flame-retardant PS materials to meet building safety standards.
Weather resistance: Improve the anti-aging ability and UV resistance of the board and extend its service life.
Insulation: Add a bubble layer or compound other insulation materials to the PS board to enhance the insulation effect.
Installation convenience: Design standardized dimensions and connection methods for quick construction.
Electronic and electrical field
Performance requirements: PS boards for electronic and electrical appliances are mainly used for housings or internal components, and need to have good insulation, heat resistance and antistatic ability.
Applicability optimization:
Insulation performance: Ensure that the PS board has a high resistance value to avoid the risk of current leakage or short circuit.
Heat resistance: Increase the glass transition temperature (Tg) of the material so that it can remain stable in high temperature environments.
Antistatic: Reduce static electricity accumulation through surface coating or adding conductive fillers to protect sensitive electronic components.
Lightweight design: Reduce weight while ensuring strength to meet the needs of portable devices.
Medical field (special applications)
Performance requirements: PS boards for medical use need to have high cleanliness, biocompatibility and chemical corrosion resistance, and are suitable for medical devices or laboratory consumables.
Applicability optimization:
Biosafety: Ensure that the material is non-toxic and harmless and will not react adversely with human tissue.
Chemical resistance: Resist the erosion of disinfectants or other chemicals to extend the service life.
Transparency: Provides a clear view for easy observation and operation.
Sterilization compatibility: Able to withstand high temperature and high pressure sterilization or radiation sterilization without damage.
Toys and daily necessities field
Performance requirements: PS boards for toys and daily necessities need to take into account safety, aesthetics and economy.
Applicability optimization:
Safety: Comply with children's toy safety standards (such as EN71 or ASTM F963) to avoid small parts falling off or toxic substances being released.
Color diversity: A rich color selection is achieved through dyeing or coating technology to enhance product attractiveness.
Cost control: Reduce manufacturing costs by simplifying the structure or optimizing the production process.

The performance requirements of PS boards in different application scenarios vary significantly. Manufacturers need to adjust the material formula, structural design and manufacturing process according to specific needs to ensure the applicability and reliability of the product.
