OPTOLINQ TMC-2100 | Optically Clear Molding Compound
TMC-2100 is developed to exhibit robust optical performance, TMC-2100IR a high IR transparent version designed for applications operating above the visible light spectrum.
OPTOLINQ TMC-2100IR | Optically Clear Molding Compound
TMC-2100IR boasts its blended chemistry system to improve IR transparency through refractive index matching and IR-transparent fillers. The transmittance shown is measured at 2 mm thick sample and will exhibit higher transmittance at a thinner samples and packages.
Inspected specimens are 1 mm thick sample cured in mold for 4 minutes at 150°C and post cured for 4 hours at 150°C.

TMC-2100IR Particle Size Distribution: Powder for Compression Molding

OPTOLINQ TMC-2100IR Powder for Compression Molding
The particle-size distribution of TMC-2100IR coarse powder is tightly centred on a median diameter (D50) of 129.9 µm. Only 10 vol % of particles are finer than 36.7 µm (D10) and 90 vol % are below 280.6 µm (D90), giving a span of 1.88 that denotes a moderately narrow, well-graded curve.
Most particles fall between roughly 40 µm and 280 µm, supplying enough fines to fill interstices without dusty handling and few oversize granules that might entrap air during mould filling. The volume-average diameter D[4,3] of 145.5 µm confirms mass clustering near the median, while a specific surface area of 29.9 m²kg⁻¹ signals moderate binder demand. Because our process controls D50 within 80–160 µm, future lots will closely replicate this flow and packing behavior.
