Enterprise Estonia investments

Wolf Group product development project

Support measure: Support for product development in companies affected by COVID-19 for the period 2019-2020
Funded by the EU in response to the COVID-19 pandemic

Project period: 1 October 2020-31 July 2023
The project involves the product developments set out below.


More people-friendly and environmentally friendly products in the context of growing market expectations

The objective here is to develop products with a low VOC (Volatile Organic Compound) content as well as products made from raw materials that are safer for humans and the environment and which meet the ever-tightening expectations/thresholds on export markets. This will lead to the development and registration of products that meet the requirements of registrations EC1+, M1, BvB, Sintef, Basta, etc. The outcome will be seven new products with a lower VOC content that have been developed taking into consideration increasingly stringent legislation and restrictions on various chemical compounds.

Fire-resistant products and products with enhanced reaction to fire

The objective here is to develop new products that improve the fire resistance of existing construction materials and structures. The outcome will be six new products that improve the fire resistance of structures and various structural units.

Development of single-component and fast-setting polyurethane foam

The objective here is to develop single-component, fast-setting polyurethane foams that speed up construction and thus reduce costs and the environmental footprint. The outcome will be two new single-component polyurethane foams.

The amount of support being allocated by Enterprise Estonia is 477,933.75 euros.

The project is supported from the European Regional Development Fund.


Wolf Group investment in resource efficiency

Summary of project

In the course of the investment, Wolf Group OÜ will purchase a new cartridge mould for joint sealants, automate the installation of the protective gloves inserted in the caps of construction foam cylinders and reconstruct the substation. Wolf Group OÜ will make production more efficient by reducing the use of raw materials and energy through the introduction of new technologies. Energy consumption will fall by 1% and the cost of reactive energy will be nil. Furthermore, Wolf Group OÜ is reducing the quantity of outsourced cartridges and will produce more on its own.

Objective and outcome of project

The objectives of the project are to install a new and more economical device instead of the current cartridge mould, to automate the insertion of gloves and to reduce the consumption of reactive energy and electricity. As a result of the project there will be less wastage, which will reduce the use of raw materials per unit of production. Furthermore, the introduction of new equipment will reduce electricity consumption, as the new devices are more efficient in electrical terms than the old ones. Moreover, there will be no costs associated with reactive energy.

The amount of support is 192,500 euros.
