Delta Glass profile• Manufacturer of
acrylic cast sheets• Production site for
Polyplastic, no sales• 18 workers• Production in 3 shifts
from Monday till Saturday• Production capacity :
1.500.000 sqm/yr ( 5000 ton PMMA)
![Page 3: Scratch resistant PMMA made possible in the Value Chain Project](https://reader031.fdocuments.in/reader031/viewer/2022011722/5870a14d1a28abeb2e8bb275/html5/thumbnails/3.jpg)
Production process• Monomer MMA
(Methylmetacrylate) is casted between 2 glass panels
• A combination of 2 Glass panels with a PVC gasket is a mould
• Polymerisation will take place in autoclaves
• The product is an acrylic sheet PMMA

Acrylic Sheets
• 2 – 12 mm range• All transparant
colours• Impact resistant
sheets• Niche product,
bubbleplex

DPI Value Chain Project : Improved properties of PMMA
• Subject 1 : Glassfiber reinforced PMMA− Improve strength of a PMMA sheet by casting monomer into a glassfiber filled mould
• Subject 2: Scratch resistant PMMA− Development of a Scratch resistant coating suitable for PMMA

Subject 1 :Glassfiber reinforced PMMAProblems :• Bonding agent in glassfiber
interfere with polymerization
• Glassfiber make it impossible to cut the sheet
• Sheets become warped, not flat, difficult to handle
• Entrapped air bubbles remains in the sheet
Solutions :• Use glassfiber without
bonding agent
• Use high pressure watercut machine
• Mould should be equally filled with fibers
• Very difficult to fit this product in our production facility. No short term solution

Subject 2 :Scratch Resistant Coating• suitable for PMMA• Trials with UV cured
coatings, not suitable for outdoor usage
• Trials with Thermo cured coatings with success
• We developed a flow coat technique
UV cured coating provided by C2Coatings
![Page 15: Scratch resistant PMMA made possible in the Value Chain Project](https://reader031.fdocuments.in/reader031/viewer/2022011722/5870a14d1a28abeb2e8bb275/html5/thumbnails/15.jpg)
Prototype Coating line• New coating line
inhouse this year only for testing
• Suitable for outdoor applications
• High scratch resistance
• With the knowledge achieved we will invest next year in a production line
