Cellular polyether, polyester with right propertiesThe customers demand decides the choice of material.ShareREAD MORE/CONTACTHideBoth cellular polyether and cellular polyester are produced in large blocks making it easier to mould the correct thickness and form. Usual names of these materials are Lamiflex and Fireflex.Cellular polyether: There is wide variety of cellular polyethers with different weights and mechanical, acoustic and thermal features. Sound absorbers, mattresses, upholstery, sealings and sponges are some examples of their fields of application. The features can vary a lot depending on the cell dimensions and the quantity of closed or semi-closed cells. Cellular polyester: Cellular polyester is similar to cellular polyether but it has a more uniform cellular structure and is oil and fat resistant. Sound absorbers and filters in environments that require oil-resistance are some examples of its fields of application. There is also a water resistant variant of this product which can be used in a multitude of ways. Daniel FermskogPhone +46 370 65 47 11 Send e-mail

Are the materials water-repellent? Some grades of cellular polyester are available in a water-repellent finish, making them suitable for use in many environments where they are exposed to moisture. Can cellular polyethylene be used as a sound absorber? Yes, several products such as Lamiflex, Fireflex and Basotect have excellent acoustic properties and are used in everything from vehicles to indoor acoustics. Can cellular polyethylene be used for seals? Yes, semi-open variants in particular, such as Isoseal, Situseal and Superseal, work extremely well as seals where flexibility and compressibility are important. Can cellular polyurethane be used in mattresses and upholstery? Yes, cellular polyurethane is commonly used in mattresses, furniture upholstery and other comfort products thanks to its flexibility and dimensional stability. Can you help us choose the right materials for an acoustic solution? Of course. We take into account requirements such as noise level, weight, fire safety, environmental impact and mechanical stress in order to recommend the right cellular polyether or cellular polyester for the application. Can you supply the materials in customised shapes? Yes, we die-cut all types of cellular polyethylene and cellular polyester to custom dimensions, shapes and thicknesses, tailored precisely to the customer’s requirements. Do the materials have a fire rating? Yes, several of our materials – Fireflex, Superseal, Isoseal and Basotect – are fire-rated in accordance with FMVSS 302 or UL94. Is cellular polyester suitable as a filter material? Yes, open-cell variants such as Bulpren and Filter FR are used as air filters and industrial filters thanks to their structural stability and PPI classification. Is it possible to laminate cellular polyethylene or cellular polyester? Yes, we can combine these materials with textiles, film or other layers to create specific functions, such as protection, a sealing surface or a wipeable surface. What is Basotect used for? Basotect is an open-cell melamine foam that is extremely lightweight and offers excellent sound absorption. It can withstand temperatures of up to +240°C and is UL94 V-0 fire-rated. What is cellular polyethylene and what is it used for? Cellpolyether is a versatile foam material available in various densities, cell sizes and with open or semi-open cells. We use it, for example, in sound absorbers, mattresses, furniture padding, seals and washing-up sponges. What is Isoseal/Situseal used for? Isoseal/Situseal is a semi-closed-cell polyether foam used as a sealant or sound absorber. It withstands temperatures from –40°C to +120°C and is fire-rated in accordance with FMVSS 302. What is Superseal and when is it used? Superseal is available in both cellular polyester (W) and cellular polyether (KD), both of which have semi-open cells. They are primarily used as seals, often in the automotive sector, and are fire-rated in accordance with FMVSS 302. What is the difference between cellular polyethylene and cellular polyester? Cellular polyester has a more uniform cell structure and better resistance to oil and grease than cellular polyether. It is often used as a sound absorber or filter in environments where chemical resistance is required. What is the temperature resistance of the materials? Temperature resistance varies: Isoseal withstands temperatures from –40°C to +120°C, Basotect up to +240°C, and bonded foam from –40°C to +120°C. The choice depends on the application. What makes bonded foam stand out? Bonded foam is recycled cellular polyurethane with good sound absorption and high density (100–160 kg/m³). It is an environmentally friendly alternative with high mechanical stability. What makes Fireflex stand out? Fireflex is an open-cell polyester foam with high fire resistance (UL-94 HF-1, FMVSS 302). The material is often used as a lightweight and effective sound absorber. When is Bulpren most suitable? Bulpren is an open-cell polyester foam and is mainly used as a filter material and for speaker protection. It is available in 10–30 PPI and provides good airflow. When should you choose Lamiflex? Lamiflex is a semi-closed-cell polyether foam developed as a sound-absorbing material. The material is lightweight, highly flexible and meets the fire safety requirements set out in FMVSS 302. Which cell materials are suitable for the automotive sector? Superseal KD, Isoseal and several semi-open-cell polyurethanes are frequently used in the automotive industry due to their fire rating and their sealing and sound-dampening properties.
