“…In scientific literature, there are an increasing number of papers related to laser processing of elastomeric and generally polymeric materials [ 1 , 2 , 3 , 4 ]. Laser microprocessing of elastomeric materials [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ] is an alternative to lithographic methods; it belongs to direct methods, using the sources of laser radiation, usually: CO 2 (wavelength 10.6 μm—medium infrared) and Nd-YAG (consecutive wave harmonics: 1064, 532, 326, and 266 nm—from near infrared to ultraviolet), also including ultrashort pulse lasers.…”

Elastomers are used as construction materials in numerous industries, and in particular the biomedical industry, mechatronics, electronics, the automotive industry, and chemical devices. The paper presents the results of tests involving the effects of microprocessing of elastomeric materials using a UV laser emitting picosecond pulses. In particular, it presents an analysis of the influence of the parameters of processing on its efficiency. The paper provides a recommendation of the most advantageous processing parameters for materials such as polyurethane and silicone (MVQ). The authors see prospects for the use of the developed technology in the techniques of sealing and microfluidisation. The final part of the paper presents examples of surface structures generated on elements made of artificial materials and the results of tests involving reduction of friction resistance of sealing rings in a pneumatic actuator.
