Pressure test paper, also called pressure sensitive paper, brings unique benefits compared with traditional pressure sensors, which makes it popular in multiple manufacturing industries. Its biggest strength is full-surface pressure mapping. Conventional pressure transducers only collect discrete data at limited measuring points and may miss local high-pressure hotspots. Pressure test paper captures pressure distribution across the whole contact area in a single test, showing overloaded or insufficient contact zones at a glance.

　　Pressure sensitive paper, or pressure test film, is categorized by measurable pressure ranges and structural types. Correct model selection is critical to obtain reliable test results. The product portfolio covers ultra-low, low, medium, high and ultra-high pressure grades, catering to different load conditions from soft contact clamping to heavy mechanical stamping. Users must select the proper grade according to the estimated peak pressure of their testing scenario.

　　Pressure test paper, also named pressure sensitive paper, features simple operation, but standardized steps are required to avoid measurement error. Before testing, confirm the estimated pressure range and select the matching film grade. Prepare scissors or cutting tools to cut the film into the shape matching the contact area.

　　Pressure sensitive paper, also referred to as pressure test paper, serves as a vital quality testing consumable across diverse industries. In automotive manufacturing, it is used to check gasket sealing pressure, fuel cell stack clamping uniformity, brake contact surfaces and bolt joint pressure distribution.

　　Pressure test paper, also known as pressure sensitive paper, has strict storage requirements to maintain its performance. Unused film relies on intact microcapsules to realize pressure response. Improper storage will cause microcapsule pre-rupture, leading to background color stains and invalid measurement.

　　Pressure sensitive paper (pressure test paper) delivers reliable results only when operated correctly. Users often encounter abnormal test phenomena such as no color development, full over-dark staining or irregular background marks. These problems can be traced to improper grade selection, wrong operation or poor storage conditions.
