The P80 Ra is a non-flowing pasty product specifically developed for Roughness Measurement.
Its initial consistency makes it a good fit for hard-to-reach surfaces like vertical or overhanging areas.
It creates semi-rigid replicas with a hardness of 80 Shore A, which do not deform during demolding. Replicas made from P80 Ra cannot withstand any extraction constraint (0%).
The P80 Ra is specifically developed for roughness control. It precisely replicates surface roughness, allowing measurement directly from the impression using a roughness tester or optical inspection device.
This plastiform is ideal for roughness control and provides accurate Ra values. If you need to determine Rt or Rz, it’s better to use a non-contact measuring device.
It can also be used to create partial impressions on simple external shapes. The impression is highly accurate but should not be subjected to extraction stress.
We do not recommend cutting P80 Ra impressions with the Double Blade Cutter because of their rigidity.
The usage of the P80 Ra is recommended for:
Indirect Roughness Controls: Replicas made of this product can be measured using a Roughness tester or optical roughness measuring devices.
Dimensional Control: As a pasty product, the P80 Ra can also be used for regular dimensional controls and is measurable with contact devices.
When applying P80 Ra, create a thick impression with a flat outer surface. This will facilitate roughness measurements.
As with dimensional inspection, degrease the area to be inspected using the DN1 before applying the product to ensure optimal results.
Looking for a complete kit to try plastiform?
The case contains all required accessories to use Plastiform. It is the best way to try our solutions for the first time!
Can a conventional Roughness Meter be used directly on the impression?
A Roughness meter should only be used on rigid products, such as the P80 Ra, which is specially developed for this application.
Do contact measurements alter the replica?
We recommend using a contact control machine exclusively with rigid impressions post-polymerization (> 80 Shore A or > 30 Shore D). Employing contact control methods on softer impressions might temporarily distort the measurements during the evaluation, though it will not cause long-term deformation as a Plastiform always goes back to the shape it copied.
Are Plastiform products compatible with all types of metal alloys?
We always recommend carrying out a preliminary test to confirm that your alloy will not adhere to the product, as we have observed several cases of incompatibility with very specific alloys, although this is very rare.
Are Plastiform products sensitive to UV light?
No, our products are not sensitive to them in the short or medium term in their traditional use.
Can an underwater impression be taken?
Impressioning can work without problems underwater, and more generally in any environment without oxygen.
What are nozzles and tips used for?
The nozzle should be attached at the end of the cartridge, ensures that the two components of the plastiform mix homogeneously before application. It is a consumable item and must be replaced after each use. The tip, which is fitted at the end of the nozzle, reduces the flow rate. This is particularly recommended for fluid plastiforms to achieve optimal application accuracy, especially in fine details. The tip is reusable and can be cut to increase the flow if needed.
What are the storage requirements?
All our products must be stored at room temperature (20°C) in their original packaging to preserve the technical characteristics indicated on the label.
What does “working time” means?
The "Working time" is the period during which a Plastiform can be altered after injection, maintaining its initial consistency. This means that the chemical reaction between the two components has not yet progressed to the point where the impression begins to harden.
What does “curing time” means?
The "curing time" is the period after which the impression can be removed from the part following its injection. This is when the impression has achieved approximately 80% of its final hardness, enabling its removal from the form to be replicated.
What does “polymerization time” means?
The "polymerization time" is the time required for the impression to reach its final hardness, such as 20 Shore A for F20, 50 Shore A for F50, etc. This indicates when the impression is fully usable, particularly for precise dimensional measurements.
