Available with different (5, 15, 25 min.) pot lives.
In case that hardener PTG 8 is used instead of PTG 1 (quantity x of PTG 1= 1.2 times the quantity of PTG 8), one will obtain cured materials with considerably improved properties with regard to elongation and resistance to tear propagation, whilst the higher viscosity of the PTG 8 will deteriorate the flowability slightly as a result of which the curing will be delayed considerably. For ProtoFlex types with a pot life of 25 minutes, we therefore generally advise our customers against working with PTG 8. Example: 100 parts ProtoFlex 190-05 + 65 parts PTG 8: Pot life 5 minutes, tensile strength approx. 17 MPa, elongation approx. 400 %, resistance to tear propagation approx. 100 N/mm.
ProtoFlex type can be mixed with each other with the aim to formulate linearly an individual hardness of between Shore A 10 and Shore A 90. ProtoFlex types can also be combined with ProtoCast types (e. g. flexibilization of ProtoCast and/or harder formulation of ProtoFlex). Here, however, it is particularly important to consider the mixing ratios with for example PTG 1 (e. g. 100 parts PF 150 + 100 parts PF 190 + 74 parts PTG 1 (20 parts + 54 parts) = rubber of Shore A 70).
