STMMA is Specifically designed for lost foam casting by CastChem.
*Each of the above products is available in 25kgs bags or 125kgs drums.
The Castchem STMMA Formulation VS EPS for Lost Foam
*CastChem developed 20 years ago an advanced casting formulation STMMA for Lost Foam, and it had been granted an American patent.
*CastChem developed STMMA-FD formulation in 2016, specially used for aluminum lost foam cast, also with a relatively low price that easy to be accepted by the foundries.
*CastChem's STMMA series contains less carbon molecules than EPS, so it can reduce or eliminate fold defects and excessive lustrous carbon in castings which has been proved by our users in China and American such as BMW,GM,and Anhui QuanChai Engine.
Lost Foam Advantages vs Traditional Casting
*Lost Foam Casting is particularly used for very complex casting. This process eliminates cores and parting lines.
*Lost Foam also improves accuracy in sizing, Casting walls can be curved or of variable thickness.
*Lost Foam casting is cost effective because it does not need as much machining as traditional casting.

P.S. (Expandable Poly Styrene) is a lightweight, rigid, plastic foam insulation material produced from solid particles of polystyrene. Expansion is achieved by virtue of small amounts of gas dissolved into the polystyrene base material during production. The gas expands under the action of heat, applied as steam, to form perfectly closed cells of EPS. These cells occupy approximately 40 times the volume of the original polystyrene bead. The EPS beads are then molded into appropriate forms suited to their application. Products made from foamed polystyrene are nearly ubiquitous, for example packing materials, insulation, and foam drink cups Feature: 1,EPS(Expandable Polystyrene) ,White Polystyrene powder,EPS Resin 2,good preserving character 3,free sample and competitive price 4.Good flame-retardant, good frothing good preserving, good binding and low heat-conducting rate.Oxygen index over 30 (testing after 7-14 days flowing) Application This Flame retardant grade EPS can be used as building-materials, materials for heat preservation, thermal insulation and for packing precision instruments.
Low Melting PET Chip is a specialized form of polyethylene terephthalate (PET) that features a lower melting point compared to standard PET chips. This property enables easier processing and expands its potential applications across various industries. It is particularly well-suited for Hot Melt Yarn Masterbatch production and serves as an extrusion-grade polymer for hot-melt adhesive and glue coating processes. Key Features: Lower Melting Point: The chip exhibits a melting temperature range of 90C to 160C, allowing for faster, more energy-efficient processing during molding or extrusion. Excellent Compatibility: It can be blended or co-extruded with other PET grades, making it versatile in a variety of manufacturing processes. Cost Efficiency: The lower energy consumption and reduced processing time lead to significant cost savings.
Product Introduction: Polystyrene (PS), abbreviated as PS, refers to a polymer synthesized by free radical addition reaction of styrene monomer, with the chemical formula (C8H8) n. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes. Product name Polystyrene Appearance Colorless and transparent thermoplastic Foreign name Polystyrene Flash point 156.3 Chemical formula C8H8n Melting point 212 Boiling point 293.4 Density 1.05g/cm Classification Ordinary polystyrene/expanded polystyrene, etc Product application: Due to its transparency, excellent rigidity, electrical and printing properties, especially its good hygiene and low cost, polystyrene has broad application prospects in food packaging. It has been widely used in various instrument casings, lampshades, optical parts, instrument parts, transparent window mirrors, transparent models, chemical acid storage tanks, acid conveying tanks, telecommunications parts, high-frequency capacitors, high-frequency insulation pads, brackets, inserts, and frozen insulation materials in the electromechanical industry, instrument and communication equipment industry, etc. It is also widely used in various daily necessities, such as bottle caps, containers, decorations, buttons, combs, toothbrushes, soap boxes, boxes, and toys.
Product Introduction: GPPS plastic is a general-purpose polystyrene plastic. Polystyrene (PS) refers to a polymer synthesized by free radical polymerization of styrene monomers. Polystyrene mainly includes four types: ordinary polystyrene (GPPS), high impact polystyrene (HIPS), expanded polystyrene (EPS), and syndiotactic polystyrene (SPS). Essential information: Product Name GPPS Characteristic Glossy and transparent Category Polymer Manufacturing method Forming processing Security Product application: GPPS plastic is mainly used to manufacture transparent food boxes, fruit plates, small tableware, etc. It can also be made into shrink film for shrink packaging of food. Product Features: GPPS is a glossy and transparent particle. Lightweight, affordable, low water absorption, good coloring properties, dimensional stability, good electrical performance, transparent products, and easy processing. GPPS is soluble in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones, and esters, but can only swell in acetone. Can withstand the action of certain mineral oils, organic acids, bases, salts, lower alcohols, and their aqueous solutions. Low water absorption rate, able to maintain its mechanical properties and dimensional stability in humid environments. Excellent electrical performance, high volume resistance and surface resistance, and not affected by temperature, humidity changes, or corona discharge. The radiation resistance is also very good. The main disadvantages of GPPS are its brittleness, low impact strength, poor heat resistance, inability to withstand boiling water, and can only be used at lower temperatures and loads. Poor resistance to sunlight and flammable. When burning, it turns black and has a special odor.
