Moisture absorption - Import export

Chemical appearance: Potassium Amyl Xanthate (PAX) is available in the form of yellowish or pale-grey crystals or in the form of free-flowing powder in the purest state. PAX is also available in the form of a solution. PAX is highly water-soluble and emits a slightly unpleasant odor that is similar to that of carbon disulfide or that of decaying cabbage. Another property of PAX is the absorption of moisture from air i.e., hygroscopic nature. Chemical application and strengths: The properties of PAX as a Xanthate make it the ideal collector for various nonferrous metallic ores. Potassium Amyl Xanthate is the perfect choice for flotation processes of nonferrous metallic ores as a strong yet non-selective collector. PAX works effectively as a flotation reagent in the flotation of oxide minerals such as oxidized sulfide, lead, and copper ores. PAX is also a popular flotation collector for copper-nickel sulfide and auriferous pyrite

Starting with the base polymer TECASINT 5011, TECASINT 5051 with 30 % glass fibre has been developed. This material is characterised by reduced thermal elongation, reduced moisture absorption and high wear strength during chip test applications in the semiconductor industry. It has good electrical insulation properties and surface hardness, and also high rigidity. The glass transition temperature is 340°C, while the maximum service temperature may be – for a short time – up to 300 °C.

TECASINT 2011 is one of the unfilled natural grades. It has a very high modulus of elasticity, high rigidity and hardness. Compared with TECASINT 1011 it has significantly reduced moisture absorption, higher toughness and better machining properties. Within the TECASINT 2000 series the material has the maximum strength and elongation, together with a high modulus of elasticity and minimal thermal and electrical conductivity. TECASINT 2011 is highly pure with low outgassing in accordance with ESA regulation ECSS Q 70 20.

Compared with the other TECASINT materials the TECASINT 4100 series exhibits extremely high thermal stability, extremely low moisture absorption and high mechanical rigidity. This is accompanied by a very high oxidative stability and increased resistance to chemicals. TECASINT 4111 has a very high thermal stability (HDT/A=470°C). Rigidity and modulus are significantly increased vis a vis conventional polyimides in a temperature range up to 400 °C. The material has minimal thermal and electrical conductivity. The plastic is highly pure with low outgassing in accordance with ESA regulation ECSS Q 70 20.

Compared with the other TECASINT materials the TECASINT 4000 series exhibits very low moisture absorption and high oxidative stability along with improved chemical resistance. Despite its high strength, TECASINT 4011 has high elongation at break and toughness. Rigidity and modulus are significantly increased vis a vis conventional polyimides in a temperature range up to 260°C. It also has minimal thermal and electrical conductivity. The plastic is highly pure and displays low outgassing in accordance with ESA regulation ECSS Q 70 20.
