Molding and Extrusion Ionomer is a subcategory of Ionomer. It is specially formulated to molding and extrusion. Its flexural modulus ranges from 3 to 55 MPa. Its tensile strength ranges from 2500 to 5400 MPa at break. Its elongation at break ranges from 300 to 700 %. Its specific gravity ranges from 0.93 to 0.96. Its coefficient of thermal expansion ranges from 100 to 170 x 10^-6/°C. Its melting temperature ranges from 81 to 96 °C. Its molding pressure ranges from 2 to 20 MPa.

Ionomer is a thermoplastic polymer. Common trade names include Aclyn, Himiran, Coathylene, Surlyn, and Escor. It has high impact strength (low temperatures), puncture and abrasion resistance, high melt elasticity, and good thermoforming properties. It also has low sealing temperatures and high sealing seam strength. It is resistant to grease, oil, and solvents. Applications of Ionomer range from tough, scratch-resistant golf balls and bowling pin covers to footwear components, glass coatings, abrasion resistant surfaces and buoys. It can be used to replace glass or crystal, and it can also be used as packaging films and sealants.
