Glass Transportation

Makevale is a leading manufacturer of acrylic bead materials, a key component used in interleaving powders for the safe storage and transportation of float glass.

Adhesive forces and chemical reactions can cause panes to stick together so strongly that they cannot be separated. Furthermore, transportation or storage creates a risk of glass surface corrosion. Interleaving powders are comprised of acrylic beads of a tight size profile with additives to prevent corrosion or staining.

It is essential that the interleaving powder is soft enough to avoid pitting the glass and has a small and specified particle size distribution. The reasons are firstly to allow a reproducible and efficient application of the powder onto the glass, and second to avoid a few large beads allowing the smaller beads to fall out when the glass is raised to the vertical position leading to glass on glass contact.

Makevale’s manufacturing technology allows the consistent production of beads with a tight, defined particle size distribution and specified flow characteristics. We are able to achieve these tight tolerances through varying surface characteristics via reagents and process, sieving, wash water type, and the addition of flow modifiers.

For strategic reasons, an interleavant powder manufacturer needed to replace their incumbent supplier and approached Makevale to replicate their entire range. We analysed the products, developed improved versions and manufactured trial quantities in less than 3 months. We then scaled up to production quantities for customer testing.

There remained a few small volume but key products which were extremely specialised. Their components were initially difficult to isolate, and required the development of a suitable manufacturing process. But Makevale thrive on such technical challenges and eventually presented the manufacturer with improved products based on a tighter specification and at a lower price than their incumbent.

Please contact our business development team if you are interested in acrylic beads suitable for interleaving powders in glass storage and transportation. We have a wide range of suitable acrylics and a proven track record in producing new acrylics with unique properties. If you would like to develop a new acrylic powder suitable for glass interleaving, our R&D team will be interested to hear from you.
