Polyvinyl alcohol - manufacture by blending

Polyvinyl alcohol (PVA) is a white to yellowish solid. PVA is a thermoplastic used as a binder or thickener in adhesives and paints. It is found in finished products such as adhesives, cosmetics and in solid board as a filler. PVA is water soluble and is therefore also used for the production of water soluble films.


Some types of PVA are biodegradable. Due to the rapid solubility in water at cold and hot temperatures to make the formulations more soluble in water.

Polyvinyl alcohol - manufacture by blending

PVA Advantages

  • Does not foam when dissolved in water
  • Excellent properties of the gas barrier film
  • Highly polar (non-ionic) versatile polymer, compatible with many ingredients.
  • Viscosity in aqueous phase which is hardly affected by pH.
  • Strong hydrogen bond for use in dispersants
  • Tolerant to inorganic and organic salt

Custom blend of water-based polymers

There are many reasons for (partially) outsourcing your blend production to Intercol. It is a growing trend that companies decide to put the responsibility of non-essential production to external partners, who have specific know-how and an efficient production process. Intercol has proven to several companies that we are a strong partner in Western Europe.

Composition of hot melt adhesives

The possible components of the hot melt adhesive formulation relate to their performance and processing properties. The main components of a hot melt adhesive and their role are:

The base polymer

It is the molecular backbone of systems, and it is used to provide inherent strength and chemical resistance as well as application characteristics.

Sticky agents

They are added to improve the initial adhesion and to modify the base polymer.

Processing oils and waxes

They are used to adjust viscosity and setting times. Tackifiers and processing materials will affect the low temperature flexibility and high temperature strength of the final adhesive.


They are used to refine certain properties such as melt viscosity, coefficient of thermal expansion, setting time, etc.


They are used to ensure resistance to oxidation - rather for the polymer in the applied state than for the final joint.

UV inhibitors

They are used to provide stability to light exposure.


Each year, we talk to hundreds of companies and manufacturers about their hot melt adhesive needs.

Availability of hot melt adhesives in Europe

Intercol is not only a producer of adhesives, but also an important adhesive distribution partner in the industry. This makes us one of the leading suppliers of hot melt products in Europe.

Intercol is able to do a full comparison for prospects and customers against the competition. Given the research history, we can usually make a good adhesive proposal on paper. Our great added value is the additional research on the properties of adhesives in our laboratory.
