Product Introduction

PP board, also known as polypropylene board, is a plastic board made of polypropylene material. It is widely used in various fields due to its excellent physical and chemical properties. The main features of PP board are light weight, corrosion resistance, impact resistance, good insulation, and high tensile strength and rigidity.

In addition, PP board also has good heat resistance and chemical resistance, can be used at higher temperatures, and is not easily corroded by acids and alkalis. Due to these advantages, PP board is widely used in billboards, packaging, mechanical equipment shields, chemical equipment protection, household goods, and electronic product shells.

When using PP board, there are some precautions that need special attention. First, try to avoid exposing PP board to strong ultraviolet rays. Long-term ultraviolet radiation may cause its surface aging and color fading. Secondly, when PP board is used in a high temperature environment, pay attention to temperature control to avoid exceeding its heat resistance limit to avoid deformation.

In addition, although PP board has good impact resistance, it still needs to be careful under high impact to prevent breakage. Finally, when processing and cutting PP board, it is recommended to use professional tools and equipment to ensure the smoothness and flatness of the cutting edge, thereby improving its use effect and aesthetics. Through reasonable use and maintenance, PP board can play its best performance and meet the needs of different fields.

Category	Item	Typical Value	Unit	Description
Basic Properties	Material	Polypropylene (PP)	-	Thermoplastic polymer derived from propylene monomers
	Density	0.90 - 0.91	g/cm³	Lighter than water; lower density compared to HDPE
	Appearance	Translucent to opaque	-	Natural color is white, can be customized
	Crystal Structure	Isotactic (most common)	-	High crystallinity for enhanced mechanical properties
Mechanical Properties	Tensile Strength (Yield)	30 - 40	MPa	Stronger than LDPE, suitable for structural applications
	Elongation at Break	≥300	%	Good ductility, though lower than some PE grades
	Flexural Modulus	1200 - 1800	MPa	Indicates stiffness; higher values mean better resistance to bending
	Hardness (Rockwell R)	80 - 100	-	Harder than PE, suitable for wear-resistant uses
	Impact Strength (Notched Izod)	2 - 6	kJ/m²	Varies with temperature; may require additives for cold resistance
Chemical Properties	Chemical Resistance	Excellent	-	Resistant to most acids, alkalis, and organic solvents, except strong oxidizers
	Solvent Resistance	Good	-	Insoluble in common solvents at room temperature, but may swell in some
	Hygroscopicity	≤0.01	%	Negligible water absorption, suitable for humid environments
Thermal Properties	Melting Point	165 - 170	℃	Higher than PE, enabling better heat resistance
	Continuous Service Temperature	-20 to 100	℃	Can maintain performance in a wide temperature range, but brittle below -20℃
	Heat Deflection Temperature (1.82MPa)	50 - 70	℃	Lower under load; reinforcing fillers can improve this value
	Coefficient of Thermal Expansion	(6 - 10) × 10⁻⁵	/℃	Higher than metals, expansion joints may be needed in large installations
Processing Properties	Molding Methods	Injection molding, Extrusion, Thermoforming	-	Widely processed using common plastic fabrication techniques
	Welding Methods	Hot air welding, Extrusion welding, Ultrasonic welding	-	Weldable, but requires proper surface preparation and technique
	Surface Adhesion	Poor	-	Surface treatment (flame treatment, corona treatment) needed for bonding
Electrical Properties	Dielectric Strength	25 - 35	kV/mm	Excellent insulator, suitable for electrical applications
	Volume Resistivity	≥10¹⁶	Ω·cm	High resistivity maintains electrical isolation
Applications	Typical Uses	Chemical tanks, Food containers, Medical devices, Electrical enclosures, Automotive parts	-	Leveraging its chemical resistance, heat resistance, and hygiene properties
Standards	International	ASTM D4101, ISO 19223	-	Commonly referenced for quality control and testing
	Domestic (China)	GB/T 12024 - 2005, GB/T 18442 - 2019	-	Chinese standards for PP products
