SMART INSULATING SOLUTIONS FOR THE PROFESSIONAL

Polyurethane Foam Polyurethane foam or OCF (one component foam) is a mixture of polyols and isocyanates in one can with the addition of a propellant. A prepolymer with isocyanate functionality is formed inside the can prior to spraying. One component foam comes in a single can. Curing occurs through a reaction with moisture from the atmosphere and substrate. The reaction is accompanied by cross-linking and an increase in volume.

Polyurethane Foam advantages - Good adhesion to most common substrates - Thermal conductivity (?-value ± 0,030 – 0,035 W/m.K) - Noise reduction - Water vapour open - Very low density = high volume from one canister (handy, cheap and “green”) - Seal and fills all kinds of shapes - Easy to use

Polyurethane Foam points of attention - Formulations can contain isocyanates - Post expansion (uncontrollable) - Temperature sensitive during application - Pressurized canister (dangerous at high temperature >50°C) - Flammable propellants - Not UV stable - Transportation limitation in vehicles

Polyurethane Foam types Within Bostik we do have different types of polyurethane foams. These types can vary per application and specification. Our mapping will be as follows: - Straw (hand held) and gun foams - DIN 4102 classified by flame behaviour - One and two component foams - Expanding foams

Hand Held and Gun Foams Application wise polyurethane foams come in two different types. We have so called hand held formulations and gun grade formulations. Hand applied polyurethane foams are equipped with a straw that can be screwed to the valve on top of the dome. The so called gun foam needs a ‘pu-gun’ to apply the material. Hand Held PU Foam advantages - Hand held polyurethane foams will have no additional costs of buying a foam gun - Simple and easy to apply Hand Held PU Foam points of attention - Difficult to dose - Should be emptied in one go to avoid blocking the straw with cured material - After flow possible Gun Grade PU Foam advantages - Easy to dose, easy to apply - No after flow from gun - Reusable - Less waste Gun Grade PU Foam points of attention - Additional costs for gun and PU cleaner
