PPS and PPS GF40 are high-performance plastics, which means they fulfill a variety of requirements in many application scenarios. But both can also be used together, if desired, for the same application. They both meet several different requirements – and in exactly the same way.
PPS and PPS Gf40 are the two plastic materials with excellent firing performance. They belong to the family of PMP plastics, which are mostly used for engineering plastic parts that must be exposed to high temperatures in the air or in the furnace or kiln, or even under ultra-high vacuum conditions.
What is PPS plastic
Polyphenylene sulfite (PPS) is a thermoplastic polymer used to make injection-molded, extruded, or blow-molded products. PPS has been the material of choice for many applications due to its excellent strength, excellent moisture resistance, and high-temperature stability.
PPS is supplied in different grades, each grade has its own properties and characteristics. The industry standard is an engineering grade that is normally used in mechanical or structural applications.
The grades of PPS are:
Grades-1: For applications where visual appearance is important, e.g. food containers or medical implements
Grades-2: For structural applications that require high impact strength and good stiffness at low temperatures. Applications include truck beds, motorcycle fairings, mobile home frames, and refrigerator liners
Grades-3: A general-purpose grade with good flexural strength and moderate impact properties. Applications include bottle caps, load-bearing panels in shipping crates, appliance housings, and automobile engine compartments.
Grade-4: For applications where extreme toughness at low temperatures are required, e.g. cryogenic tanks for liquefied gases.
Grade-5: For applications in which a high degree of physical/mechanical/chemical resistance is required for continuous service temperatures above 180°.
When you want to PPS plastic sheet, you need to find a reliable supplier, such as KEWARD plastics.
What is PPS GF40
The polyphenylene sulfite (PPS) family of plastics is a group of engineering resins that have been used for over 50 years. These materials are known for their good balance of physical, mechanical, and chemical properties. They are mainly used in electrical applications such as connectors, switches, and high voltage power cables. PPS Gf40 is a glass fiber-filled variant of the polyphenylene sulfite family.
Glass fibers have been used in plastic products since the 1950s. The composite is produced by mixing chopped glass fibers and polyphenylene sulfite resin as a matrix using a twin-screw extruder. The composite is then heated to form a homogeneous mass that can be formed into sheets. The glass fibers are aligned along the direction of extrusion during the process and provide reinforcement to the product once it has cooled down to room temperature. Glass fiber reinforced PPS plastics are often referred to as PPS Gf40 in technical circles due to the fact that the glass content is 40%, meaning that 40% of the final product consists of glass fibers. It is also common to refer to these products as PPS-GF40 or just GF40 when shortening the name of the material.
According to PPS GF40 rod, the material comes in black and natural color and it can be injection molded into complex shapes with a smooth surface finish. This material has a density of 1.15g/cm3 and a melting point of 425°C (777°F). It exhibits excellent dimensional stability over a wide range of temperatures (-40°C to +130°C)
How to choose between PPS and PPS GF40
A lot of people are quite confused about the differences between the PPS and PPS GF40 plastics. Both have a great reputation for durability, but there are some important considerations to think about before you purchase.
The differences between PPS and PPS GF40 are quite simple. It all starts with the process used to make these plastics.
In the case of PPS, both the fiberglass cloth and resin are heated in a mold. In the case of PPS GF40, however, only the fiberglass is heated prior to placement in the mold. While this process is slightly different than that used to produce standard PPS plastic, it does not result in any major difference in performance.
Paintball masks constructed with either material will be just as durable as those made with standard PPS plastic. The only real difference is the price – while PPS masks are usually more expensive than their GF40 counterparts due to the extra steps involved in their construction, they can also be quite a bit lighter than those constructed with this material.
Also, the two material is really hard to machine, ask PPS plastic machining before you make your decision.
The biggest difference between these two materials is price, therefore if you’re looking for a budget paintball mask then you should probably look for one made from PPS GF40 plastic.
