Materials for Earmoulds
The earmould can be manufactured from a wide range of materials depending on intended use and the patient’s personal preference. Earmould materials range in hardness, elasticity, colour and non-allergenic properties and every earmould can be tailored using these options to meet the needs of the earmould user.
Hard Acrylic (PMMA)
Hard acrylic is cosmetically appealing, produces a nice smooth finish. Its the most commonly used material and can be produced in the widest variety of colours. Moulds made from hard acrylic are the easiest to modify at the point of fitting. Hard acrylic is the most cost effective choice in material.
Soft Acrylic (PEMA)
Soft acrylic is cosmetically appealing like hard acrylic but it softens with the body temperature. Soft acrylic is available in the same wide range of colours as hard acrylic. Due to the increase in material softness the mould adjusts more to the ear canal resulting in a more comfortable fit. This also results in an improved acoustic seal compared to hard acrylic.
Hard and Soft Acrylic combined
This combination, where the tip of the earmould is made of soft acrylic is a popular choice as it combines the cosmetic properties and ease of fitting of hard acrylic with added comfort and acoustic sealing of soft acrylic.
UV Light cured
Fotoplast is a trade name of Dreve Gmbh and is cured using ultra-violet light. This material does not contain methyl methacylate (MMA) and as a result is more biocompatible than hard and soft acrylic. This material produces a hard earmould similar to hard acrylic.
Silicone
Silicone makes the most comfortable moulds while also providing an excellent acoustic seal and reducing the likelihood of an allergic reaction. There are 4 types of standard silicone each with different properties, rated using the “shore” rating system. Starting at 25 Shore for an extremely soft mould, and increasing to 70 shore (softer than Soft Acrylic). Silicone materials should be chosen by their shore strength to match the requirements of the patient.
Microflex
Microflex silicone is a trade name from Frish Gmbh and is the most commonly used silicone earmould material. Microflex is rated as 30 shore (very soft) and is highly suitable for children. MicroFlex is available in a range of colours.
Catamaran
Catamaran is produced by Frish Gmbh and due to its low density is specially formulated to float in water. This material is generally used for water sports and swimming.
Sonic Sil
Sonic Sil is Sonic Labs exclusive material. Sonic Sil is rated with a shore strength of 42, providing an optimum balance between standard silicone and acrylic materials. This material is ideal for all ages and all types of hearing loss due to the uniqueness of the shore strength. Sonic Labs have chosen to use this fine grade material as its widely used for Maxillo-facial prosthesis and has excellent biocompatibility, reducing the likelihood of an allergic reaction. Sonic Sil can be produced in a wide range of colours.
Micropor
Micropor silicone is a trade name from Frish Gmbh and is a harder 70 shore material, more suitable for older patients. As standard this material has a matt finish, though a gloss finish is available. Micropor earmoulds are available in a range of colours.
Silastic
Silastic silicone is a trade name for Dow Corning and is available in a crystal clear material only. It has a shore strength rating of 30 shore.
Biopor
Biopor silicone is a trade name of Dreve Gmbh and is available in 20, 25, 40 and 70 shore. We provide all shore strengths and colours available from Dreve.
Bioplast
Bioplast silicone is a trade name of Detax Gmbh and is available in 40 and 60 shore rating.
High Bio Compatibility Earmoulds + Gold Plated Earmoulds
Gold plating a hard acrylic earmould provides the most non-allergenic option for those with very sensitive skin. This is the most suitable choice when all other materials have been exhausted.
Coloured, Marbled and Glitter Earmoulds
If you want to personalise your earmould you can choose from a range of colours and glitters types. If you can’t choose one colour you can have 2 or 3 coloured marbled together.
Please note – colours may vary slightly based on batch and material choice. The shades shown here may be slightly different.
