WHAT IS ICE?

ICE is a high-performance tape, it can be used in a wide variety of products for various market segments - anywhere, in fact, where there is a need for superior strength, safety, weight saving or durability.

Weight-for-weight, ICE is 11 times stronger than steel. It is made of a special type of UHMWPE (Ultra High Molecular Weight Polyethylene), making it not only the strongest UHMWPE tape available in the world, but it also has a higher modulus and better UV resistance, creep properties and thermal-aging performance than any other UHMWPE-fibres.

ICE is the most sustainable UHMWPE product available, being made in an environmentally friendly, solvent-free process. As a result, the tape contains no additional processing aids or solvent residue. The thermoplastic nature of UHMWPE means that it can also be easily recycled.

Sails made with ICE keep their shape even under severe forces, they are not damaged by ultraviolet light, and they can be endlessly folded and unfolded. The flat form of ICE tape lends itself naturally to the flat surface of sails.

UNIQUE PROPERTIES

ICE offers users a unique combination of properties. It is strong – 11 times stronger than steel, weight for weight. It is remarkably light, durable, weathers well, performs well under temperature changes and is made in an environmentally friendly way - all of which means it is a sustainable solution.

VERY HIGH MODULUS

Tensile modulus (elastic modulus) is a measure of the stiffness of an elastic isotropic material, and is used to characterize a material’s rigidity. ICE has a very high modulus (i.e., it is very rigid), especially for a material that has such low density. ICE also has a higher modulus than other UHMWPE materials as shown in the bottom table.

TESTING

CHEMICAL RESISTANCE

ICE, naturally, has a good chemical resistance against a wide variety of chemicals. Prolonged exposure even at temperatures of 70°C does not harm the properties of ICE. Among the chemicals that ICE can resist are 10% Sodium Hydroxide, 10% Sulphuric acid and water.

SUPERIOR WEATHERING

Fibers are weakened by exposure to ultraviolet light (sunlight), a fact that needs to be taken into account in the initial design. In outdoor tests (ISO 877), under direct weathering at an angle of 5° facing south without protection (Northern hemisphere), ICE tape not only showed less performance loss than other high performance yarns, but also less than conventional UHMWPE yarn. See top table.

PERFORMANCE AT CRYOGENIC TEMPERATURES

The strength of UHMWPE materials is affected by temperature. As the graph below shows, their tensile modulus and the breaking tenacity both fall off considerably at higher temperatures. However, unlike other high performance materials, UHMWPE materials do not become brittle at low temperatures. On the contrary, they tend to become stronger. See bottom table.
