   Carbon dioxide: 400–800 cm 3 ·mm ... Products made from polycarbonate can contain the precursor ... Typical products of sheet/film production include applications ...

3. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Although single layer polycarbonate sheeting is more flexible than polycarbonate in twinwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.72 g/cm^2 [6] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through. [7]

4. Polycarbonate (functional group) - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate_(functional...

   A polycarbonate is an oxocarbon dianion consisting of a chain of carbonate units, where successive carbonyl groups are directly linked to each other by shared additional oxygen atoms. That is, they are the conjugate bases of polycarbonic acids , the conceptual anhydrides of carbonic acid , or polymers of carbon dioxide .

5. Carbon-fiber reinforced polymer - Wikipedia

   en.wikipedia.org/wiki/Carbon-fiber_reinforced...

   The fracture toughness of carbon fiber reinforced plastics is governed by the mechanisms: 1) debonding between the carbon fiber and polymer matrix, 2) fiber pull-out, and 3) delamination between the CFRP sheets. [8] Typical epoxy-based CFRPs exhibit virtually no plasticity, with less than 0.5% strain to failure.

6. Biodegradable plastic - Wikipedia

   en.wikipedia.org/wiki/Biodegradable_plastic

   A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...

7. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   PMMA ignites at 460 °C (860 °F) and burns, forming carbon dioxide, water, carbon monoxide, and low-molecular-weight compounds, including formaldehyde. [ 17 ] PMMA transmits up to 92% of visible light (3 mm (0.12 in) thickness), [ 18 ] and gives a reflection of about 4% from each of its surfaces due to its refractive index (1.4905 at 589.3 nm ...
