Microencapsulation from Encapsys

Generally speaking, microencapsulation is the process of putting a microscopic wall around a core substance. But there are a lot of different methods to get the job done. Physical encapsulation methods like spray drying or fluid bed coating may be appropriate for some applications. While chemical encapsulation methods such as coacervation, interfacial polymerization and in situ polymerization may be appropriate for others.

When deciding which method to use, we start by focusing on your needs and challenges. We look at how you want your product or process to perform and what outcome you want to achieve. We also learn as much as we can about the material you'd like to encapsulate and how you want it released. Once we have a full understanding of the material and the criteria for success, we can pick the encapsulation method that will fit your needs best. So no matter what method we choose, you can expect consistent high-quality and high-payload capsules. We can say this with confidence because we have over 50 years of experience with large-scale production volumes of microcapsules.

Our tight control over the core-to-wall ratio allows us to maximize the capsule load, with core materials typically accounting for 80% to 95% of the capsule. Other microencapsulators deliver a typical payload of around 50%. We can also tightly control the capsule diameter, ranging from sub-micron to over 1000 microns. We pride ourselves in our ability to predictably scale up from prototype to commercial volume – think thousands of tons of microcapsules shipping to destinations all over the world – in a very short period of time.

All in all, it's about enabling and enhancing the benefits of your products or the processes you use to make them.
