MIRAFOAM Λ(LAMBDA) is a high-performance thermal insulation material that meets the performance requirements of the next generation. By adding special technology to MIRAFOAM we were able to achieve thermal conductivity of 0.022W/m-K, which exceeds the limit of thermal insulation performance of extruded polystyrene foam. With the growing demand for carbon neutrality and the further raising of insulation standards for houses there are high expectations for MIRAFOAM Λ.

MIRAFOAM is an extruded polystyrene foam used for thermal insulation of homes and buildings. CFC gas is not used as a foaming agent.　Its thermal conductivity is approximately 1/50 that of concrete making it an excellent energy-saving heat insulator. It also has excellent waterproofing and toughness.
MIRAFOAM can be easily cut with a saw or cutter knife, making it easy to install and work with.

The world's only low-density foamed polycarbonate, MIRAPOLYCAFOAM combines the excellent mechanical properties of a tough engineering plastic with lightweight properties. It can be molded or composited with other materials and performs over a wide temperature range (-40°C to 120°C). It also exhibits outstanding termite resistance and is used as a heat insulator for housing foundations. It is a human- and environment-friendly product as no chemicals are used.

JSP can provide pre-cut insulation materials if the pre-cut drawings are provided to us. This eliminates the need for processing insulation materials at the construction site, thereby reducing waste, construction period, and labor costs.

STYRODIA is expandable polystyrene beads, whose molded products have excellent heat insulation and shock-absorbing properties. It is widely used in Japan for food packaging materials, cushioning packaging materials, building insulation materials and civil engineering materials. Used molded products can be recycled as raw materials for a wide variety of re-manufactured products. The material recycling rate in Japan is more than 50%, and 90% if thermal recycling is included.

FOAMCORE combines the expansion and blow molding process simultaneously into a single process tool, that offers superiority in terms of lightweight, strength, thermal insulation and recyclability. FOAMCORE consists of a solid outer layer and an expanded core, expanding the possibilities for mono-material components. It has been applied to prefabricated bathrooms, automotive parts and marine floats.

ACRYACE is a non-foamed extruded sheet that can be made of various resins such as MS or polystyrene. ACRYACEMS is an extruded sheet of MS resin copolymerized with MMA (methyl methacrylate monomer) and SM (styrene monomer). It is used in the following areas.
[Application Examples]
- Optical field (lens installation base plates, diffusion plates, etc.)
- Industrial fields (frozen/refrigerated showcase faceplates, etc.)
- General (picture frame faceplates, poster panels, etc.)
- Construction (interior doors, stairway panels, etc.)
ACRYACE UV is transparent sheet made of MS resin with good adhesion to UV-curable ink. ACRYACE DS is a design-oriented extruded sheet with excellent design characteristics such as a checkered pattern and is used as a glass substitute for interior doors, furniture and commercial space displays.

MIRAMAT is a low-density foamed polyethylene sheet developed by JSP using the world's first non-cross-linking method to continuously extruded polyethylene into a sheet while forming numerous independent bubbles.
It has excellent shock absorption, moderate slipperiness, elasticity, heat insulation, moisture-proofing and waterproofing properties. A wide variety of density is available. Products such as bag-making, punching, cutting and laminating can be provided through secondary processing.

P-BOARD is a foamed polypropylene board with persistent antistatic properties that can be used in a wide range of applications. It meets a variety of needs by adding persistent antistatic, shock-absorbing and conductive functions.
Excellent processability facilitates cutting, punching and heat molding. It continuously prevents the generation of static electricity due to friction during transportation and the function does not deteriorate even after repeated washing or strong friction. Relatively high heat resistance among general-purpose resin products and can be used under high temperatures.
It is environmentally friendly, hygienic and safe. It is also easy to recycle and does not emit toxic gases when incinerated.

MIRASTICK is a low-density profile extruded polyethylene foam. It has excellent impact resistance and durability. It is used as a protective material for furniture and pillars, and can be easily cut with cutters or scissors.
