Tensilestrength 40 to 50 MPa GPPS thermoplastic polymer type optimized for industrial fabrication and product durability

Product Description:

General Purpose Polystyrene (GPPS) is a versatile and widely used thermoplastic polymer known for its excellent clarity, ease of processing, and balanced mechanical properties. As a member of the polystyrene family, GPPS offers a range of attributes that make it suitable for various applications in industries such as packaging, consumer goods, electronics, and automotive components.

One of the key characteristics of General Purpose PS is its glass transition temperature, which ranges between 90 to 100°C. This temperature range indicates the point at which the polymer transitions from a hard and relatively brittle state to a more rubbery and flexible state. The relatively high glass transition temperature of GPPS ensures that it maintains dimensional stability and mechanical integrity under moderate heat conditions, making it ideal for products that require heat resistance during use or processing.

The density of GPPS typically falls between 1.04 and 1.06 grams per cubic centimeter (G/cm³). This density range reflects the polymer’s compact molecular structure, contributing to its rigidity and strength. The moderate density of General Purpose Polystyrene also aids in achieving lightweight components without compromising durability, which is particularly beneficial in applications where weight reduction is critical, such as in consumer electronics housings and packaging materials.

In terms of mechanical performance, GPPS exhibits an Izod impact strength of approximately 1.7 Kg-cm/cm. While this indicates moderate impact resistance, it is sufficient for many everyday applications where the material must withstand occasional impacts or drops. The balance of rigidity and impact strength makes General Purpose PS a preferred choice for products like disposable cutlery, CD cases, and various household items that demand a combination of stiffness and toughness.

As a thermoplastic polymer, GPPS can be repeatedly melted and reshaped without significant degradation, enabling efficient recycling and reprocessing. This thermoplastic nature also facilitates a variety of processing methods that are commonly employed in manufacturing. Injection molding is one of the primary techniques used with GPPS, allowing for the production of complex shapes with high dimensional accuracy and smooth surface finishes. This makes it an excellent material for creating detailed components and intricate designs.

Extrusion is another widely used processing method for General Purpose Polystyrene. Through extrusion, GPPS can be formed into sheets, films, and profiles, which are then utilized in applications such as packaging materials, display panels, and protective covers. The material’s clarity and surface quality are well-preserved during extrusion, making it suitable for transparent or decorative products.

Thermoforming is also applicable to GPPS, where heated sheets of the polymer are shaped into desired forms using molds. This process is commonly used to manufacture trays, containers, and other packaging solutions. The ease of thermoforming, combined with GPPS’s good dimensional stability and surface finish, enables cost-effective production of high-quality packaging items that meet consumer and industrial demands.

Overall, General Purpose Polystyrene (GPPS) stands out as a reliable and efficient material choice across many sectors due to its favorable combination of thermal, mechanical, and processing properties. Its glass transition temperature of 90 to 100°C, density in the range of 1.04 to 1.06 G/cm³, and Izod impact strength of 1.7 Kg-cm/cm provide a balanced profile suitable for diverse applications. The thermoplastic nature of GPPS ensures versatility in manufacturing through injection molding, extrusion, and thermoforming, making it a preferred polymer for producing a wide array of products with clear, rigid, and durable characteristics.

Applications:

The General Purpose Polystyrene (GPPS) product, available under the brand name GPPS with model numbers 525 and 550, is a versatile thermoplastic material widely used across various industries. Certified with ISO 9001 and ISO 14001, this product guarantees quality and environmental management standards, making it a reliable choice for manufacturers and designers alike.

GPPS, also referred to as General Purpose PS or GP5250/N, is well-known for its excellent clarity, rigidity, and ease of processing. Its Izod impact strength of 1.7 Kg-cm/cm ensures sufficient durability for many everyday applications. Due to its chemical resistance properties, GPPS is resistant to acids and bases but has poor resistance to solvents, which should be considered when selecting this material for specific uses.

One of the primary application occasions for GPPS is in the packaging industry. Its transparency and rigidity make it ideal for creating clear, protective packaging solutions that showcase the product inside while providing structural integrity. This is particularly valuable for packaging consumer goods, electronics, and food items that require both visibility and protection.

Another common scenario for using GPPS is in the production of disposable cutlery. The material’s ease of molding and cost-effectiveness allow manufacturers to produce lightweight, yet sturdy forks, knives, and spoons for single-use purposes. This application benefits from GPPS’s thermoplastic nature, enabling efficient mass production without compromising on quality.

GPPS also finds significant use in the creation of CD cases and other similar media storage containers. Its clarity and rigidity protect valuable discs while allowing easy visibility of the contents inside. This application highlights GPPS’s ability to combine aesthetics with functionality in consumer products.

Model making is yet another important application scenario for GPPS. Hobbyists, architects, and designers utilize GPPS for crafting detailed prototypes and models due to its ease of cutting, shaping, and painting. The material’s consistent performance and smooth surface finish make it ideal for precision work and visual presentations.

With a minimum order quantity of 1 TON and packaging details of 1000KG per package, GPPS is conveniently supplied to meet both small-scale and large-scale production needs. The price range of 1000-1200 USD per ton reflects its competitive market positioning, while delivery times between 5 to 45 days and payment terms via TT provide flexibility and reliability for customers worldwide.

In summary, GPPS General Purpose PS (GP5250/N) is a high-quality, ISO-certified thermoplastic material that excels in packaging, disposable cutlery, CD cases, and model making applications. Its balance of strength, clarity, and chemical resistance makes it an excellent choice for a wide range of industrial and consumer product scenarios.
